POLYETHER-MODIFIED POLYSILOXANE COMPOSITION AND METHOD FOR PRODUCING THE COMPOSITION AND METHOD FOR MEASURING TOTAL AMOUNT OF CARBONYL IN THE POLYETHER-MODIFIED POLYSILOXANE COMPOSITION |
摘要 |
PROBLEM TO BE SOLVED: To provide a highly refined polyether-modified polysiloxane composition not substantially developing odorization with time in a mixed system of water with a (polyhydric) alcohol. SOLUTION: The polyether-modified polysiloxane composition comprises an organopolysiloxane-polyoxyalkylene copolymer obtained by hydrosilylation reaction of an organohydrogenpolysiloxane with a polyoxyalkylene having carbon-carbon double bonds at terminals. In the polysiloxane composition, (1) a total unsaturated degree measured according to JIS K-1557 is≤0.00010 meq/g and (2) a carbonyl total amount expressed in terms of propanal measured by a specific method is≤100 ppm and (3) an index of ionic impurity total amount obtained by a specific method is preferably≤30μS/m.
