PCT No. PCT/US85/01105 Sec. 371 Date Jan. 22, 1987 Sec. 102(e) Date Jan. 22, 1987 PCT Filed Jun. 11, 1985 PCT Pub. No. WO86/07369 PCT Pub. Date Dec. 18, 1986.A method for producing mercaptan terminated liquid polymers with increased chemical reactivity and reduced odor is disclosed which involves heating the polymeric liquid material under conditions which avoid oxidation and depolymerization of the material while removing at least 50 weight percent of low molecular weight mercaptan compounds to produce a stripped polymer material having an increased cure rate and reduced obnoxious mercaptan odor.
