9,10-Dihydro-9-oxa-10-phosphaphenanthrene 10-oxide-based oligosiloxane as a promising damping additive for methyl vinyl silicone rubber (VMQ)

For the first time, we report the damping effect of a novel 9, 10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide (DOPO)-based oligosiloxane abbreviated as DOPO-PMVS on methyl vinyl silicone rubber (VMQ) elastomers. Designed DOPO-PMVS was synthesized by means of hydrophosphination reaction and studied by FT-IR, 1H NMR, 29Si NMR, 31P NMR, and thermogravimetric analysis. The effect of added DOPO-PMVS on damping, mechanical, and thermal properties of...
