Concentrates containing specific functionalised diblock copolymers serve as effective additives for improving the cold flow behaviour of fuels and oils, the copolymers being derived from a terminally-unsaturated intermediate polymer obtained via a metallocene process involving hydrogen.

Additives for fuels and oils comprising functionalised diblock copolymers

Materials having structure (1), wherein R and Rmay be the same or different and each independently represents an alkyl or aryl group, X may be hydrogen or a Cto Calkyl group which may be branched or linear and wherein the aromatic ring substituent joined to polymer B is positioned meta or para to the aromatic ring substituent joined to polymer A and, wherein polymer A is a non-polar polymer formed by metallocene catalysis and polymer B is a polymer formed by radical catalysis of a polar monomer are used as polymer additives particularly to improve the compatibility of mixtures of polymers. 

Use of polymers comprising two segments as polymer additives

Concentrates containing specific functionalized diblock copolymers serve as effective additives for improving the cold flow behavior of fuels and oils, the copolymers being derived from a terminally-unsaturated intermediate polymer obtained via a metallocene process involving hydrogen.

Additives for fuels and oils comprising Functionalised diblock copolmers

The packaging industry desires adhesive compositions having a fast set time, such as those setting in less than five seconds from a molten state at conventional packaging operating temperatures to a solid or quasi solid having favorable Dot T-Peel, set time, and/or fiber tear adhesion properties. Polymer based adhesives performing within this window are a favorable alternative to conventional formulated adhesives. The provided adhesive compositions exhibit a favorable balance of properties such as high adhesive strength, wide temperature operating window, and fast set time. Provided are adhesive compositions composed of a polyolefin composition comprising at least about 50 mol % polypropylene, at least one wax and at least one wax modifier.

Polyolefin adhesive compositions and method of making thereof

An adhesive blend is described that can include a semi-crystalline copolymer of propylene and at least one comonomer selected from the group consisting of ethylene and at least one Cto C&#x3b1;-olefin, the copolymer having a weight average molecular weight (Mw) from about 15,000 to about 200,000; an melt index (MI) from about 7 dg/min to about 3000 dg/min as measured by ASTM D 1238 (B), and a (Mw/Mn) of approximately 2. Various production processes are also described. Also described are adhesive compositions and methods for making adhesive compositions having polymers or polymer blends with melt flow rates (MFRS) equal to and above 250 dg/min. at 230&#xb0;C. Certain specific embodiments of the invention involve the use of a free radical initiator, e.g., a peroxide.

Polypropylene-based adhesive compositions

A process for preparing a functionalized polymer composition and a functionalized polymer composition. The process comprises the steps of providing a hydrocarbon resin, a polyolefin and a graft monomer, and dispersing the hydrocarbon resin in the polyolefin, followed by adding the graft monomer under shear to prepare the functionalized polymer composition. The polyolefin can comprise a polyethylene polymer or a C3 to C40 polymer having a molecular weight (Mw) of at least 20000.

Composition and manufacture thereof

Embodiments of the present invention relate to article comprising 1) a functionalized component, 2) tackifier, and 3) an olefin polymer comprising one or more C3 to C40 olefins, optionally one or more diolefins, and less than 5 mole % of ethylene having a Dot T-Peel of 1 Newton or more, a branching index (g') of 0.95 or less measured at the Mz of the polymer; and an Mw of 100,000 or less; where the functional component is selected from the group consisting of functionalized polymers, functionalized oligomers and beta nucleating agents; and where the Gardner color of the adhesive does not change by more than 7 Gardner units when the adhesive has been heat aged at 180&#xb0; C. for 48 hours as compared to the Gardner color of the unaged composition.

Polyolefin adhesive compositions and articles made therefrom

Adhesive compositions and a method for selecting adhesive compositions are disclosed herein. Preferred adhesives generally have small domains and/or a homogeneous domain distribution. The method of selecting adhesives is based on size and distribution of the domains.

Adhesive compositions and method for selection thereof

A composition suitable for an air barrier such as an automotive tire innertube, innerliner, and aircraft tire innertube or innerliner, curing bladders, and other pneumatic devices is disclosed. The composition comprises an elastomer, a processing oil, and a grafted resin component.

Elastomeric blend for air barriers comprising grafted resin components

An adhesive blend is described that can include a semi-crystalline copolymer of propylene and at least one comonomer selected from the group consisting of ethylene and at least one Cto C&#x3b1;-olefin, the copolymer having a weight average molecular weight (Mw) from about 15,000 to about 200,000; an melt index (MI) from about 7 dg/min to about 3000 dg/min as measured by ASTM D 1238(B), and a (Mw/Mn) of approximately 2. Various production processes are also described. Also described are adhesive compositions and methods for making adhesive compositions having polymers or polymer blends with melt flow rates (MFRs) equal to and above 250 dg/min. at 230&#xb0; C. Certain specific embodiments of the invention involve the use of a free radical initiator, e.g., a peroxide.

Ethylene unsaturated ester copolymers combined with a resin are disclosed for use in the sealing layers of laminates and films.

Heat sealable compositions and uses thereof

Multilayer protective films that adhere well to many different surfaces and can be removed without leaving residues are provided. The films consist of a polyolefin backing layer(s) and an adhering layer consisting of an ethylene unsaturated ester copolymer layer containing a resin. The films have good tensile strength and stiffness at minimum thickness and can be produced by blown film and cast processes, mono and co-extrusion. The films are particularly useful for protecting automobiles during transportation and storage, a masterbatch of the resin in an ethylene polymer or copolymer to facilitate co-extrusion of the multilayer films is also provided.

Protective films

Films disclosed herein contain a base or core layer comprising a first polypropylene, a second polypropylene, and a hydrocarbon resin. The base layers may also include other additives as described below. The first polypropylene is preferably a high crystallinity polypropylene having a melting point above about 155&#xb0; C. or a polypropylene having a polydispersity (Mw/Mn) greater than about 4.0. The second polypropylene may be any conventional polypropylene, preferably having a melting point below about 160&#xb0; C. and/or a polydispersity less than about 5.0.
