DEFINITION

Classification: 156/331.2

N only in unlinked side-chain or side-ring:

(under subclass 331.1) Subject matter wherein the finished (e.g., cured, etc..) resin adhesive has a polymer backbone free of nitrogen, the nitrogen being found only in side-chains (e.g., polyacrylonitrile, etc..) or in side-rings (e.g., polyvinylpyridine, etc..) which are not cross-linked to other polymer backbone material.

331.6, for bonding processes using similar adhesive but without curing after assembly.

327, 333 and 334, for bonding processes using other vinyl-type resins.
