Abstract:

MODULUS-TEMPERATURE DATA, MODULUS-TIME DATA AND GLASS TRANSITION TEMPERATURES HAVE BEEN OBTAINED FOR THE FOLLOWING COPOLYMER SYSTEMS 1 ETHYLENE DISULFIDE AND ETHYL ETHER DISULFIDE, 2 ETHYLENE DISULFIDE AND ETHYL FORMAL DISULFIDE, AND 3 ETHYLENE DISULFIDE AND ALPHA PARAXYLENE DISULFIDE. MASTER STRESS RELAXATION CURVES WERE CONSTRUCTED FOR POLYETHYL FORMAL DISULFIDE, POLYPARAXYLENE DISULFIDE AND POLYETHYLENE TETRASULFIDE AND SHOW A MARKED RESEMBLANCE TO THOSE OBTAINED FOR AMORPHOUS HYDROCARBON POLYMERS.
