DEFINITION

Classification: 44/395

With additional synthetic nonhydrocarbon polymer:

(under subclass 393) Compositions which contain, in addition to the compound having plural -C(=O)O- groups, an additional compound which is a synthetic polymer having elements other

than carbon and hydrogen.

(1) Note. An example of an ingredient combination provided for herein is the combination of ethylene-vinyl acetate copolymer together with acylated polystyrene.
