Low out-gassing room temperature curable rubbery polymer, preparation thereof and device comprising same

摘要

Disclosed is polymer materials essentially free of silicone capable of room-temperature thermal cure and when cured having low modulus, low out-gassing rate. The material before cure typically comprises three components: (i) a cationically curable component comprising the backbone of a hydrocarbon-based rubber material essentially free of carbon-carbon double bonds and triple bonds; (ii) a hydroxyl-containing component having at least two hydroxyl groups per molecule; (iii) an initiator component having essentially no volatility at room temperature and also yield products after polymerization that have minimal or no volatility at room temperature; (iv)an optional viscosity adjustment component either homopolymerizable or capable of copolymerizing with the photo or electron beam curable material component of (i); and (v) an optional non-alkaline inert filler. Also disclosed are process for making such cured material and devices comprising such cured polymer materials.
