Surface modification of methylvinylsilicone rubber vulcanizates with polyhedral oligomeric
silsesquioxanes functionalized using chloride groups (POSS-Cl)

Polimery 2016, No 4, 272

Summary
The effect of surface modification on the properties of methylvinylsilicone rubber vulcanizates (MVQ) was investigated. Polyhedral oligomeric silsesquioxanes (POSS) functionalized with chloropropyl, chlorobenzyl and chlorobenzylethyl groups were used as modifying agents. The crosslink density, mechanical and barrier properties, thermal stability, surface free energy and oxygen induction time of the impregnated MVQ vulcanizates were investigated. It was found that the modification led to an improvement in the composite properties. All the investigated samples showed good mechanical strength, reduced gas permeability and increased surface hydrophobicity. Also, the thermal stability of the vulcanizates was increased as aresult of the modification.
