Aqueous free radical emulsion polymerization |
摘要 |
In the aqueous emulsion free radical polymerization of dienes and copolymerization of dienes and vinyl monomers using mercaptan modifiers there is added at at least 75% conversion a large amount of mercaptan modifier as compared to that previously added and the polymerization is stopped at about 90-99+% conversion to provide processable polymers having a reduced amount of or no gel.
