DEFINITION

Classification: 508/470

Nitrogen attached indirectly to the-C(=O)O- groups by nonionic bonding (e.g., lauryl methacrylate-diethylaminomethyl-acryl copolymer, etc.):

(under subclass 469) Compositions wherein the -C(=O)O- groups of the polymer are attached indirectly to nitrogen by nonionic bonding.
