DIP-FORMED SYNTHETIC POLYISOPRENE LATEX ARTICLES WITH IMPROVED INTRAPARTICLE AND INTERPARTICLE CROSSLINKS

摘要

A synthetic polyisoprene latex emulsion has pre-vulcanization composition and post vulcanization composition The pre-vulcanization composition comprises soluble sulfur with high S8 ring structure that is catalytically broken by a zinc dithiocarbamate The latex emulsion has post-vulcanization composition with accelerators that crosslink inter-particle region during post vulcanization cure cycle The films exhibit high tensile strength, tensile modulus, tear strength, burst pressure and burst volume.
