DEFINITION

Classification: 428/461

(under subclass 457) Product in which a layer adjacent the metal layer contains an (addition polymer from unsaturated monomers*).

(1) Note. This is the locus for products in which the addition polymer is substituted with heterocyclic or nitrogeneous radials, but see (2) Note below. Included under this definition are acrylamide, coumarone or vinyl pyridine polymers and patents claiming a layer of such material will be classified here.

(2) Note. A laminate of metal and a nitrile of an addition polymer from unsaturated monomers is classified with the ester and halide.

463, for a laminate of metal and a nitrile of an addition polymer from unsaturated monomers; and see (2) Note above.
