DEFINITION

Classification: 424/78.32

Heterocyclic monomer:

(under subclass 78.31) Subject matter wherein the solid polymer is derived from a heterocyclic monomer; e.g., a composition to control the proliferation of bacteria contains a polymer derived from the condensation of 1, 4-dichloro-2-butene and 1, 4-bis-(N-homopiperidino)-2-butene, etc.
