ABSTRACT:
Hydroxyl-terminated liquid polymers having an aliphatic polymeric backbone and sulfide linkages near the terminal portions of the polymer molecule are prepared by polymerizing (1) at least one vinylidene monomer having at least one terminal CH.sub.2 .dbd.C< group per monomer molecule, together with (2) a mixture of at least one hydroxyl-containing disulfide and at least one hydroxyl-containing trisulfide. Use of the above disulfide-trisulfide mixture permits viscosity control during polymerization with substantially less disulfide required than if the disulfide alone were used, and the resulting polymers have less odor and discolor less upon heating than if the disulfide alone were used.
