Liquid silicone rubber base polymer compositions having improved color are prepared by reaction of fumed silica reinforcing filler with a silazane, and without drying the silazane-treated filler, an aliphatically unsaturated silicone is added, heated to above 80°C, and then further aliphatically unsaturated silicone is added. The compositions have improved whiteness and color reproducibility. |
