Class Information
Number: 521/40
Name: Synthetic resins or natural rubbers -- part of the class 520 series > Synthetic resins (class 520, subclass 1) > Process of treating scrap or waste product containing solid organic polymer to recover a solid polymer therefrom
Description: Subject matter under Class 520, ... involving (a) process of recovery or producing solid organic synthetic polymer from polymeric scrap or waste product, or (b) process of preparing solid organic synthetic polymer from polymeric scrap or waste product by degradation of the polymeric scrap or waste product to monomer or low molecular weight prepolymer of a physically unseparated (i.e, nonfractionated) mixture thereof which is then reacted with another chemical species to generate another solid synthetic organic polymer.
