DEFINITION

Classification: 526/219.2

N=N or N-N group-containing compound is a catalyst admixed with at least one other catalyst, co-catalyst, or accelerator, e.g., redox catalyst, etc.:

(under subclass 218.1) Subject matter wherein the N=N or N-N group-containing compound is part of a catalyst system, i.e., admixed with another catalyst, co-catalyst or accelerator (e.g., 1, 1-dimethylhydrazine and hydrogen peroxide, azobisisobutyronitrile and benzoyl peroxide, etc.).

(1) Note. Included herein also are those systems wherein a monomer is first complexed with a catalyst and the complexed monomer is copolymerized in the presence of a free radical initiator with at least one other monomer, e.g., zinc chloride-acrylonitrile complex copolymerized in the presence of benzoylperoxide with 2-methyl-1-pentene, etc.
