<p>Phenyl containing siloxane fluids are added to transparent thermoplastic polymers to give transparent thermoplastics having improved internal lubrication. For example, PhSi(OMe)3 is equilibrated with (Me2SiO)x to give a fluid containing 28 percent by weight phenyl radicals, a PhSiO3/2 to Me2SiO ratio of 0.72 and an OMe to Si ratio of 0.78. This fluid is added to polystyrene in amount of 1 percent by weight to give a transparent plastic which exhibits no bleed and has excellent surface lubricity. </p> |
