Disclosed is a thermoplastic melt-mixed composition including: a) a polyamide resin; b) 0.50 to about 5.0 weight percent of one or more amino acid selected from the group consisting of primary amino acids and secondary amino acids; said amino acid having no hydroxyl groups and no more than one carboxylic acid; optionally, c) one or more polyepoxy compound including at least two or more epoxy groups; d) reinforcing agent; e) polymeric toughener; and f) further additives; wherein the weight percents of components a), b), c) d) e) and f) are based on the total weight of the thermoplastic melt-mixed composition. Also disclosed are processes for making the compositions.

Thermoplastic melt-mixed composition with amino acid heat stabilizer

Compositions comprising polyoxymethylene polymers and at least one organopolysiloxane polymer. Adding organopolysiloxane polymers to polyoxymethylene polymers provides compositions that exhibit at least a 50 percent reduction in melt viscosity compared to the melt viscosity of an identical, melted composition lacking the organopolysiloxane polymer, and promote easier molding of the compositions into complex article shapes.

Polyoxymethylene compositions

Disclosed is a thermoplastic melt-mixed composition including: a) a polyamide resin; b) a polyetherol compound provided by reacting: b1) one or more polyepoxy compound having at least two or more epoxy groups; and b2) one or more polyhydric alcohols having two or more hydroxyl groups; c) 10 to 60 weight percent of reinforcing agent; d) 0 to 30 weight percent polymeric toughener; and e) 0 to 10 weight percent further additives. Also disclosed are molded parts derived from the composition.

Thermoplastic melt-mixed composition with polyetherol heat stabilizer

Disclosed is a thermoplastic melt-mixed composition including: a) a polyamide resin; b) a poly(amino acid)-polyol compound provided by reacting: b1) one or more amino acids selected from the group consisting of primary amino acids and secondary amino acids and combinations of these; the amino acid having no more than one hydroxyl group; and b2) one or more polyepoxy compound comprising at least two or more epoxy groups; the poly(amino acid)-polyol compound having a range of at least 10 percent conversion of epoxy equivalents of component (b1) up to, but excluding, the gel point of the components b1) and b2) and c) reinforcing agent; and, optionally, d) polymeric toughener; and f) further additives. Processes for making the composition are also disclosed.

Thermoplastic melt-mixed composition with epoxy-amino acid compound heat stabilizer and processes for their preparation

A composite sheet comprises a substrate and a multi-layer coating on its outer surface, the coating comprising a metal layer and an outer polymeric layer formed from a precursor comprising a polymerizable composition that includes an olefin group and a moisture curable group, such as an isocyanate or silane group. The function of the polymeric layer includes protecting the metal layer from corrosion. A production process for the composite sheet includes depositing the precursor and exposing it to both beam radiation and moisture, which respectively promote polymerization and curing at different sites of the precursor. The amenability of the isocyanate or silane functionality to moisture-promoted coupling promotes substantially full conversion and curing of the precursor, even of portions of the substrate that are geometrically shadowed from incident beam radiation.

Method for producing metalized fibrous composite sheet with olefin coating

Blends comprising 65-95 wt % poly(trimethylene terephthalate-co-sebacate), 5 to 35 wt % polylactic acid and a chain extender are provided that exhibit greatly increased melt strength compared to that of poly(trimethylene terephthalate-co-sebacate) alone. Such improvements allow these compositions to be processed readily by melt-blowing, which is useful for packaging and for preparing items such as biodegradable garbage bags.

Copolyester blends with improved melt strength

A composite sheet is manufactured by depositing a multi-layer coating on the outer surface of a substrate, the coating comprising a metal layer and an outer polymeric layer formed from a precursor comprising a composition capable of being polymerized and/or cross-linked by free-radical processes. After the precursor is applied, the composite sheet is exposed to beam radiation and ozone, which both promote conversion of the precursor. The function of the cured polymeric layer includes protecting the metal layer from corrosion. The use of both beam radiation and ozone promotes substantially full conversion and curing of the precursor, even in portions of the substrate that are geometrically shadowed from incident beam radiation.

The present invention is a composition that may be used for sealing applications in the manufacture of electronic devices.

Organosilicon compounds are described which are prepared from epoxy-functional silanes and monocarboxylic acids. The compounds are useful in coatings, adhesives, and sealants, and the like.

Preparation and use of reactive organosilicon compounds

This invention relates to rapid curing coating compositions that are particularly useful for automotive OEM and refinish applications. The coating composition includes a binder component that contains a novel highly branched copolyester polyol, and a crosslinking component that contains conventional crosslinking agents, such as polyisocyanate and melamine. This invention is also directed to a process for producing coatings from the rapid curing coating compositions. These compositions are especially useful in providing for mar resistant and flexible coatings.

This invention relates to a process for controlling the architecture of copolymers of at least two unsaturated monomers, made by free-radical polymerization in the presence of a cobalt-containing chain transfer agent, including the control of molecular weight, degree of branching and vinyl end group termination, by varying at least one of the variables of molar ratio of monomers, their relative chain transfer constants, polymerization temperature and degree of conversion and amount of cobalt chain transfer agent; and polymers made thereby.
