DEFINITION

Classification: 525/403

Solid polymer 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:

(under subclass 50) 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.).

(1) Note. This subclass includes solid polymers prepared from a multiplicity of reactants all of which contain a single 1,2-epoxy group.

(2) Note. Excluded from this subclass are any 1,2-epoxy reactants which contain a plurality of methylol or methylol derivative groups. See the Glossary for the definition of "methylol derivative".

(3) Note. This subclass includes homo- or co-polymers of only 1,2-epoxy reactants containing a single 1,2-epoxy group.
