Abstract: A PROCESS IS DISCLOSED FOR PRODUCING A NEW SERIES OF ADDITION HOMO-AND CO-POLYMERS FROM MONOMERS SUCH AS EPISULPHIDES, WITH ALKALI METAL HALIDE CATALYSTS (E.G. LII) IN A POLAR SOLVENT BALANCED BETWEEN DONOR STRENGTH AND DIELECTRIC CONSTANT (E.G. HEXAMETHYLPHOSPHORAMIDE) WITH A CATALYST MONOMER MOLE RATIO RANGING FROM 0.001% TO 20% AND AT A TEMPERATURE IN THE RANGE FROM -20 TO 20*C.

Abstract: 1. PROCESS FOR THE PREPARATION OF EPISULPHIDE PLYMERS WHEREIN AN EPISULPHIDE MONOMER IS CONTRACTED, AT A TEMPERATURE IN THE RANGE OF -80 TO 150*C, WITH A CATALYSTCOCATALYST REACTION PRODUCT WHEREIN: THE CATALYST IS A MEMBER OF THE GROUP CONSISTING OF (1) ALUMINUM HYDRIDES REPRESENTED BY THE FORMULA:

A1HXY.Z

WHEREIN X AND Y, THE SAME OR DIFFERENT, ARE SELECTED FROM HYDROGEN, HALOGEN AND RESIDUES OF ALIPHATIC OR AROMATIC SECONDARY AMINES AND Z IS A LEWIS BASE SELECTED FROM ETHERS AND AMINES WHICH MAY BE ABSENT WHEN X AND/OR Y REPRESENT A SECONDARY AMINE RESIDUE; AND (2) MIXED HYDRIDES REPRESENTED BY THE FORMULA:

ME(ME''H4)N

WHEREIN ME'' IS A NUMBER OF THE GROUP CONSISTING OF A1, B AND GA, ME IS A NUMBER OF THE GROUP CONSISTING OF LI, K, RB, CS, CA, MG, BE, SR AND BA, AND N IS 1 TO 3; THE COCATALYST IS A POLYREACTIVE COMPOUND SELECTED FROM THE GROUP CONSISTING OF SULPHOXIDES, SULPHONES, OXIMES, NITRO-OR NITROSO-DERIVATIVES OF ALKYL OR ARYL HYDROCARBONS, PHOSPHORAMIDES, AND CONTAINING (A) AT LEAST TWO ACTIVE HYDROGEN; (B) AN ACTIVE HYDROGEN AND A GROP REPRESENTED BY C=O, N=O, S=O, P=O, C=S, P=S AND C$N; (C) AT LEAST TWO GROUPS SELECTED FROM P=O, P=N, C=O, N=O, S=O, C=S, P=S, C$N, AND N=S; (D) AT LEAST ONE GROUP REPRESENTED BY N=N-.
