DEFINITION

Classification: 526/63

(under subclass 1) Subject matter under Class 520, ... wherein heat exchange or reduction of particle size of a polymerizing polymer is effected by direct contact of said polymerizing polymer with an inert-solid mass which solid is

not an internal part of the polymerization apparatus or of the processing apparatus.

(1) Note. "Inert-solid mass" includes steel shot and ceramic rollers.

(2) Note. This subclass does not include indirect cooling or heating (e.g., cooling outside of reactor so as to cool reactor contents, etc.).
