Class Information
Number: 525/403
Name: Synthetic resins or natural rubbers -- part of the class 520 series > Synthetic resins (class 520, subclass 1) > Mixing of two or more solid polymers; mixing of solid polymer or sicp with sicp or spfi; mixing of sicp with an ethylenic agent; mixing of solid polymer with a chemical treating or ethylenic agent; or processes of forming or reacting; or the resultant product of any of the above operations > Solid polymer is derived from 1,2-epoxy compound containing only one 1,2 epoxy group as sole reactant and wherein none of the reactants contains a plurality of methylol groups or derivatives thereof
Description: Subject matter involves processes of mixing a solid polymer derived only from 1,2-epoxy compounds all of which contains only a single 1,2-epoxy group and none of which contains a plurality of methylol or methylol derivative groups with an additional solid polymer with specified polymer-forming ingredients, with a specified intermediate condensation product, with a chemical treating agent or with an ethylenic reactant; processes of reacting the above mixtures; or products resulting from the mixing or reacting processes (e.g., polyepihalohydrin, ethylene oxide-epihalohydrin copolymer, etc.).
