PREPARATION OF OPTICALLY TRANSPARENT CURABLE POLYORGANOSILOXANE |
摘要 |
Compositions yielding optically clear silicone elastomers are obtained by preparing a homogeneous mixture comprising a liquid polydiorganosiloxane containing at least two vinyl or other ethylenically unsaturated radicals per molecule and a finely divided silica filler treated with a hexaorganodisilazane and then adding additional hexaorganodisilazane in an amount equal to at least 5 percent of filler weight. The blending is preferably carried out using a high rate of shear and volatile materials are removed by heating the composition under reduced pressure. |
