ABSTRACT:
Phenyl containing siloxane fluids are added to transparent thermoplastic polymers to give transparent thermoplastics having improved internal lubrication. For example, PhSi(OMe).sub.3 is equilibrated with (Me.sub.2 SiO).sub.x to give a fluid containing 28 percent by weight phenyl radicals, a PhSiO.sub.3 /2 to Me.sub.2 SiO ratio of 0.72 and an OMe to Si ratio of 0.78. This fluid was added to polystyrene in amount of 1 percent by weight to give a transparent plastic which exhibits no bleed and had excellent surface lubricity.
