DEFINITION

Classification: 424/78.31

Polymer from ethylenic monomers only:

(under subclass 78.08) Subject matter wherein the designated organic active ingredient (DOAI) is a solid synthetic polymer derived from ethylenic monomers only; e.g., a fungicidal composition containing a solid polymer prepared from the condensation of 1, 4-bis-(dimethylamino)-2-butene and 1, 4-dichloro-2-butene, a composition for decreasing urinary calcium content containing a solid polymer derived from vinyl benzenesulfonic acid, etc.

(1) Note. See subclass 78.17 for the definition of an ethylenic monomer.
