Poly (phenylmethylsiloxane), terminated with divinyl groups, is a special structured organic silicon polymer with vinyl functional groups at both ends of its molecular chain. This polymer provides excellent thermal stability and mechanical properties due to its combination of phenyl and methyl groups. Diethylene end capping facilitates further crosslinking reactions and is widely used in the manufacturing of high-performance elastomers, sealants, and adhesives.
