DEFINITION

Classification: 521/50.5

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:

(under subclass 50) 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.

(1) Note. To be classified herein the composition to be polymerized or reacted must have a photoiniitator photosensitizer claimed in addition to the polymer to be treated or the monomers to be polymerized.
