DEFINITION

Classification: 428/520

(under subclass 515) Product in which at least one of the contiguous addition polymer layers contains an addition polymer from an unsaturated monomer which is in the form of

an ester, a nitrile, or a halide.

(1) Note. The addition polymer* may be derived from a monomer which includes an ester, halide or nitrile; or the polymer* itself may be treated to introduce an ester, halide, or nitrile radical.
