Promotion of the flame retardancy of 9,10-dihydro-9-oxa-10
As a phosphorus flame retardant, 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) contains a biphenyl ring structure and a phenanthrene ring structure (Luo, 2017 ), in particular introducing a side phosphorus group in the form of a cyclic O P O bond, and thus displays better flame retardancy and greater thermal and chemical stability
9,10-Dihydro-9-oxa-10-phosphaphenanthrene 10-oxide-based
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
