摘要：

In the reported experiment, liquid sulfur-olefinic system reactions at 140 degree C forming crosslinked polysulfide polymers have been investigated. A systematic approach to the characterization and some structure-property studies on these new polymeric materials has been presented. The olefinic systems of interest are endo- and exo-dicyclopentadiene and an oligomeric alkenyl polysulfide. Equimolar S//8-olefinic system copolymers are amorphous and they show no tendency for sulfur crystallization. A correlation has been drawn between chemical structure and glass transition temperature of the copolymers and terpolymers. Mechanical properties and, in particular, chemical stress relaxation of the crosslinked polysulfide polymers have been investigated.
