DEFINITION

Classification: 521/46

Treating polymer derived from a monomer containing only carbon, hydrogen, and halogen or only carbon and halogen; or treating a polymer which has been derived from at least one hydrocarbon and which has been subsequently halogenated:

(under subclass 40.5) Subject matter wherein the scrap or waste product contains a halogenated hydrocarbon.

(1) Note. The sequence of obtaining the halogenated polymeric scrap or waste product, i.e., whether the halogenated polymer was obtained by polymerizing a halogenated monomer or by halogenating the polymer itself, is considered to be immaterial. Note, however, the polymeric scrap or waste product must be halogenated before the scrap

or waste product is treated to recover or produce the solid polymer to be classified herein.

41, for a process of treating a waste or scrap material where said waste or scrap material contains a halogenated hydrocarbon.
