DEFINITION

Classification: 524/455

Halogen containing polymer:

(under subclass 452) Subject matter wherein an asbestos DNRM is admixed with a halogen containing solid polymer.

(1) Note. The halogen herein may be introduced into the polymer subsequent to its formation as by halogenation or the halogen atom may be part of the original reactant or monomers, e.g., vinyl chloride, etc.
