DEFINITION

Classification: 522/6

Compositions to be polymerized or modified by wave energy wherein said composition contains at least one specified rate-affecting material; or processes of preparing or treating a solid polymer utilizing wave energy in the presence of a least one specified rate-affecting material, e.g., nitrogen containing photosensitizer, oxygen containing photoinitiator, etc.:

(under subclass 1) Subject matter wherein said process or composition to be polymerized or modified requires, in addition to the wave energy source, at least one specified rate-affecting material.

(1) Note. A rate-affecting material is a material which either affects the rate of reaction, permits reduced amount

of wave energy, increases or decreases the degree of polymerization, cure, cross-linking, or grafting, or scavenges or provides storage stability of reactive materials or inhibits reaction; and includes photoinitiator, photosensitizer, activator, dark storage stabilizer, accelerator, inhibitor, or initiator reducing agent, retarder, photoreducible dye, sensitizing auxiliary, electron donor, generator, or curing catalyst.

(2) Note. A curing agent is presumed to be a cross-linking agent and is not considered to be a rate-affecting material. A curing catalyst, on the other hand, is considered to be a rate-affecting material.

(3) Note. A specified rate-affecting material is a rate-affecting material (see (1) Note) wherein at least one of the chemical atoms can be deduced with certainty. The following are examples of specified rate-affecting materials: benzophenone, oxygen containing curing catalyst, and a metal oxide containing inhibitor. The following are examples or rate-affecting materials which are not specified: a metal containing rate-affecting material, an organic containing rate-affecting material, an inorganic catalyst, an organometallic catalyst, a Lewis acid or base catalyst, a Ziegler catalyst.

(4) Note. A compound not claimed although solely disclosed as a rate-affecting material is considered to be a proper specified rate-affecting material. For example, a claim drawn to a process of preparing a solid polymer in the presence of wave energy and a metal oxide is disclosed as functioning in a catalyst capacity.

(5) Note. Unless disclosed to the contrary, a benzophenone or derivative thereof is presumed to be a specified rate-affecting material though not claimed or disclosed as having catalytic activity.
