Class Information
Number: 521/50.5
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. > Compositions to be polymerized by wave energy in order to prepare a cellular product wherein said composition contains a rate-affecting material; or compositions to be modified by wave energy to prepare a cellular product wherein said composition contains a rate-affecting material; or processes of preparing or treating a solid polymer utilizing wave energy in order to prepare a cellular product
Description: Subject matter under Class 521, ... including one of the following: (a) processes of polymerizing a monomer to from a cellular solid polymer in the presence of wave energy; (b) processes of reacting a cellular solid polymer with a chemical reactant in the presence of wave energy in order to produce a modified polymer; (c) processes of treating a cellular solid polymer with wave energy wherein the wave energy causes a chemical reaction to precede; (d) polymerizable compositions to be treated with wave to form a cellular product wherein a photoinitiator or photosensitizer is or either specifically or nominally.
