HYDROXYL-CONTAINING LIQUID POLYMERS AND PROCESS FOR PREPARATION THEREOF USING A MIXTURE OF AT LEAST ONE HYDROXYL-CONTAINING DISULFIDE amp; AT LEAST ONE HYDROXYL- CONTAINING TRISULFIED

摘要

-22-ABSTRACT OF THE DISCLOSUREHydroxyl-terminated liquid polymers having analiphatic polymeric backbone and sulfide linkages near theterminal portions of the polymer molecule are prepared bypolyermizing (1) at least one vinylidene monomer having atleast one terminal CH2=C group per monomer molecule,together with (2) a mixture of at least one hydroxyl-con-taining disulfide and at least one hydroxyl-containingtrisulfide. Use of the above disulfide-trisulfide mixturepermits viscosity control during polymerization with sub-stantially less disulfide required than if the disulfidealone were used, and the resulting polymers have less odorand discolor less upon heating than if the disulfide alonewere used.
