Class Information
Number: 521/77
Name: Synthetic resins or natural rubbers -- part of the class 520 series > Synthetic resins (class 520, subclass 1) > Cellular products or processes of preparing a cellular product, e.g., foams, pores, channels, etc. > Preparing a cellular product by decomposition of a solid polymer; or process of forming a composition containing a solid polymer which decomposes so as to subsequently form a cellular polymer, or composition therefrom
Description: Subject matter wherein cell formation is achieved or initiated by decomposing in whole or part a solid synthetic polymer so as to form cells in an additional polymer or to form cells in the polymer undergoing decomposition.
