The present invention encompasses manufacturing polysiloxane polyether copolymers using esters without any hydroxyl groups thereon, organohydrogen silanes and unsaturated polyoxyalkylene polyethers. Said esters are of low volatility and high boiling point and have at least eight carbons. The proce ss yields clear copolymer solutions and do not need to have the ester solvent stripped. Also taught are novel compositions incorporating the ester solvent to make the copolymer and the copolymer and the ester solvent.
