摘要:
A method of polymerizing organosiloxane monomers to produce high molecular weight polymers having a relatively narrow range of molecular weights, which includes drying the monomers to a selected moisture content of 10 ppm or less by moisture transfer contact with a desiccant at temperatures below the polymerization temperature prior to polymerization.
