Well treatment fluids, and methods for treating wellbores or fracturing subterranean formations, which include acrylamide polymer or copolymer crosslinked with one or more crosslinkers and one or more iron-containing compounds are provided. The fluids and methods may be used to carry proppants into fractures and to increase fluid recovery in hydraulic fracturing applications

Cross-linked acrylamide polymer or copolymer gel and breaker compositions and methods of use

Methods for fracturing a subterranean formation penetrated by a well bore are provided, the method comprising the step of injecting a well treatment fluid into the well bore at a pressure and flow rate sufficient to fracture the subterranean formation, wherein the well treatment fluid comprises one or more iron-containing compounds and one or more booster compounds. The methods can be used to reduce viscosity and to facilitate the decomposition of acrylamide-containing polymers.

Boosters for breakers containing iron compounds

The present disclosure relates to a method and composition for increasing wet and/or dry strength of a paper product. The method comprises adding a composition comprising at least one polymer having a molecular weight more than 0.5 million Dalton and a degradation agent to a pulp suspension, and forming said paper product.

Composition for use as a paper strength agent

Gel compositions comprising an acrylamide polymer or copolymer crosslinked with dialdehyde, methods to produce the gel compositions, wellbore treatment fluids comprising the gel compositions, and methods of treating a well bore comprising injecting the gel compositions, are provided. In the drilling, completion, and stimulation of oil and gas wells, well treatment fluids are often pumped into well bore holes under high pressure and at high flow rates causing the rock formation surrounding the well bore to fracture.

Gel compositions for hydraulic fracturing applications

Methods and well treatment fluids for fracturing a subterranean formation penetrated by a well bore are provided, the method comprising injecting a well treatment fluid into the well bore at a pressure and flow rate sufficient to fracture the subterranean formation, wherein the well treatment fluid comprises an iron-containing breaker compound. The methods can be used to reduce viscosity of well treatment fluids.

Breakers containing iron compounds and their methods of use

A thermoplastic additive composition comprises an acetal compound and at least one co-additive. The acetal compound can be the product of the reaction between an alditol or a C-substituted alditol and a benzaldehyde. The co-additive can be a fatty acid amide compound, a fatty acid ester compound, and/or a fluoropolymer. A thermoplastic composition comprises a thermoplastic (e.g., one or more polyolefins) and an additive composition as described above.

Additive composition and thermoplastic compositions comprising the same

A thermoplastic additive composition comprises an acetal compound and at least one co-additive. The acetal compound can be the product of the reaction between an alditol or a C1 substituted alditol and a benzaldehyde. The co-additive can be a fatty acid amide compound, a fatty acid ester compound, and/or a fluoropolymer. A thermoplastic composition comprises a thermoplastic (e.g., one or more polyolefins) and an additive composition as described above.

A thermoplastic polymer composition comprises a thermoplastic polymer and a nucleating agent. The nucleating agent comprises a compound conforming to the structure of Formula (I), Formula (II), or Formula (III) 

Thermoplastic polymer composition

It is possible to improve significantly the optical performance of diacetal or DBS-based nucleating or clarifying agents using a co-additive. Haze is a measure of the lack of clarity in a thermoplastic or plastic material. A low level of haze is usually quite desirable, and nucleating/clarifying agents are designed to reduce the degree of haze in a plastic or thermoplastic material. A co-additive may be used in connection with a nucleating/clarifying agents in a polymer or copolymer to achieve even greater results in terms of improved clarity (reduced haze), or in terms of a higher crystallization temperature (Tc) of the polymer. A method for reducing haze in polymer articles using a co-additive composition in addition to nucleating and clarifying agents is disclosed.

Co-additive compositions and methods for applying co-additive compositions into nucleated polymer compounds

Chemical additives disclosed for reducing 'plate-out' which have applications in polymers, such as polyolefins. It is possible to provide for a composition and a process for producing parts, sheet and film from polyolefin extrusion applications wherein the polyolefins are processed with a minimal quantity of 'plate-out.' A polyolefin composition may contain a sorbitol-based clarifying system of a derivative of Dibenzylidene, along with one or more co-additives to achieve a reduction in undesirable plate-out.

Method and compositions for reducing plate-out in the manufacture of plastic articles

Diacetals of sorbitols and xylitols are employed in polyolefins as nucleating agents. Diacetals of sorbitols and xylitol nucleating agents may be provided in granular or powder form from hoppers or mixing equipment into polyolefins during the formation of polymeric compositions and polymeric articles. Flow of diacetals of sorbitols and xylitols is improved by the use of certain silicas, in certain defined weight percentages. Submicron size range silica compounds may provide excellent flow enhancement properties when blended and used with diacetals of sorbitols and xylitols powder compounds. A hydrophobic silica mixed with diacetals of sorbitols and xylitols compounds also may provide enhanced flow properties for such mixture, as compared to mixtures using hydrophilic silica. Loading ranges of silica may be important in improving the flow of diacetals of sorbitols and xylitols compounds.

Silica-containing nucleating agent compositions and methods for using such compositions in polyolefins

Nucleating agent compounds are used in polymers, such as polypropylene, to improve both the properties and processing characteristics of the polymer. Some nucleating agents may be used also as clarifiers to reduce the visual haze in finished polymeric articles, thereby increasing clarity of finished polymeric articles. Compounds of a carboxylate salt which employ a combination of an amide group and a metal cation salt perform well as nucleating agents, and provide substantial clarity benefits in a polymer. Other compounds of the invention may employ metal carboxylate salts in combination with an ester group. In other embodiments of the invention a dimer of such compounds may be employed.

Metal carboxylate salt nucleating or clarifying agent compounds and related polymer compositions and methods

Clarified polyolefins such as polypropylene are used widely to make polymer articles, containers, and the like. Such articles may be manufactured by the injection of molten polymer into a mold or forming device in manufacturing processes at high rates. A clarified composition is provided to achieve optimized clarity and organoleptic performance at lower processing temperatures and/or within a polypropylene resin having a higher melt flow rate.
