Abstract: The present invention relates to high melt swell partially neutralized alpha olefin acid copolymers. It also relates to a process for making such high melt swell polymers as well as for covalently crosslinking other polar copolymers including non-neutralized acid copolymers and non-polar alpha olefin polymers by using a minor amount of metal acrylate, particularly sodium or zinc acrylate.

Abstract: A slush molding process in which the moldable thermoplastic composition powder dosed to the mold is prepared by blending ethylene carboxylic acid copolymers or ionomers with ethylene/glycidyl acrylate or methacrylate copolymer and cross-linking promoter at a temperature and for a time that does not cause significant cross-linking prior to dosing to mold, which is held for sufficient time and temperature to cause cross-linking in-situ, and optionally, other additives including release agents.

Abstract: This invention concerns a process for imparting corrosion and creep resistance to a coating prepared from a particulate polymer composition and applied from a fluidized bed or by electrostatic spraying over metal substrates. The process of the present invention provides for maintaining the content of acid functionality of an acid-functionalized semicrystalline or acid-functionalized amorphous particulate polymer of the particulate polymer composition within a desired range. The acid functionality on the particulate polymer can be maintained, by crosslinking and/or neutralizing, within a desired range of the acid content which results in imparting corrosion and creep resistance to the coating applied over the metal substrates. Neutralizing the acid functionality of the polymer component results in hardening the coatings resulting therefrom. The process further provides for adding anticorrosive pigments to the composition for further improving corrosion resistance of the resultant coatings.

Abstract: Moisture-curable, melt-processible, graft copolymers are obtained by reacting certain direct ethylene copolymers having copolymerized therein a glycidyl containing comonomer, with a specific aminosilane, N-tert-butylaminopropyl trimethoxysilane. The compositions are useful as hot-melt moisture-curable adhesives, as co-extrudable adhesives, and in wire and cable and several other applications.

Abstract: A pressure sensitive adhesive composition which can be applied by hot melt techniques to one surface and adhered to a second surface by contact at ambient temperature, to thereby bond the two surfaces together. The adhesive composition is made of certain ethylene/n-butyl acrylate copolymers together with tackifier and optionally, plasticizer.

Abstract: Moisture-curable melt-processible adhesives are obtained by reacting certain ethylene copolymers containing an alkyl acrylate and a carefully limited amount of a carboxylic acid with a stoichiometric amount of an epoxy-silane. A process of preparing the moisture-curable melt-processible adhesives in the absence of solvent is also available.
