DEFINITION

Classification: 526/60

(under subclass 59) Subject matter wherein a polymerization process parameter is altered in response to the composition

or composition property and wherein the composition property is other than density, per se.

(1) Note. Included within the definition of composition or composition property is the determination of the identity of a component or the relative amount of a component in a stream, electrical conductivity, redox, potential, pH measurement, molecular weight, melt index, optical properties, etc.
