DEFINITION

Classification: 524/505

Solid block or solid block-type copolymer with other solid polymer, SICP or SPFI:

(under subclass 502) Subject matter wherein the NRM together with a solid block or block-type copolymer and an additional solid polymer, SICP, or SPFI is present.

(1) Note. See the Class 520 Glossary for a definition of the term "block or block type copolymer".

(2) Note. For purposes of this subclass, the block or block-type copolymer need not be derived from ethylenic reactants only. It is sufficient for purposes of this subclass that a solid polymer derived from ethylenic reactants only be present.
