CO-CURED COMPOSITIONS OF AMINE-TERMINATED LIQUID POLYMERS AND VINYLIDENE-TERMINATED POLYMERS AND PROCESS FOR PREPARATION THEREOF

摘要

Co-cured compositions are prepared readily by mixing (1) 100 parts by weight of at least one amine-terminated liquid polymer having a carbon-carbon backbone and (2) from about 80 to about 120 parts by weight of at least one vinylideneterminated polymer having a carbon-carbon, polyether or polysulfide polymeric backbone. The compositions undergo a soft cure readily at room temperature without addition of catalysts or crosslinking agents. The compositions are useful as caulks, sealants and potting compounds.
