DEFINITION

Classification: 522/5

Processes of forming or modifying a solid polymer by wave energy wherein a temperature less than 0xC (32xF) or greater than 250xC(482xF) is employed; or compositions therefore:

(under subclass 1) Subject matter involving a temperature less than 0xC (32xF) or greater than 250xC (482xF); or compositions therefore.

(1) Note. The temperature conditions required must involve a direct relationship with wave energy. For instance treatment of a material by wave energy and subsequent physical treatment at the temperature lower than 0xC is not proper subject matter for this subclass.

(2) Note. A process performed while "frozen" or under "cryogenic" conditions will be placed herein unless there is a disclosure that the temperature is greater than 32xF.

(3) Note. This subclass also provides for those compositions perfected so as to be utilized in a process involving the requirements of this subclass.
