Prospect of 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide-based oligosiloxane in the preparation of high damping methyl phenyl vinyl silicone rubbers with broad temperature range

The introduction of fillers/additives into polymer matrices is a practical and effective method for preparation of damping materials. In the current work, a designed 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide-based oligosiloxane (DOPO-PMVS) was used as an additive to improve the damping properties of methyl phenyl vinyl silicone rubber (PVMQ). The preparation of high damping PVMQ elastomers with broad temperature range has been...
