Abstract:
A method for the preparation of an organopolysiloxane-grafted polysaccharide compound which comprises the steps of:(a) dissolving, in an organic solvent, a polysaccharide compound having carboxyl groups in the molecule and an epoxy-terminated organopolysiloxane compound represented by the formulaEp--(--SiR.sub.2 --O--).sub.n --SiR.sub.3,in which the subscript n is a positive integer in the range from 3 to 200, each R is, independently from the others, a monovalent hydrocarbon group or a halogen-substituted monovalent hydrocarbon group and Ep is a 2-(3,4-epoxycyclohexyl)ethyl group, to give a uniform solution; and(b) heating the solution at a temperature in the range from 60 to 200.degree. C. to effect a reaction between the carboxyl groups in the polysaccharide compound and the epoxy groups in the organopolysiloxane compound.
