Abstract
Abstract Disclosed are a polysaccharide derivative having the structure: <IMAGE> and a polysaccharide graft polymer having the structure: Sacch-O-(G)m-(M)-n, wherein Sacch- is a polysaccharide; m is zero or one; G is the residue of a polymerizable, unsaturated monomer which is bonded to the polysaccharide in an ether or ester linkage; n is greater than one; M is the residue of one or more polymerizable, unsaturated, monomer(s), at least one of which is a siloxane-containing monomer, which have been grafted to the polysaccharide by free radical polymerization; R is an organic group which is bonded to the polysaccharide by an ether or ester linkage and to the silicon by a carbon-silicon linkage; R1 is a straight or branched C1-C6 alkyl or alkenyl group, or an aryl, aralkyl or alkaryl group; and R2 and R3 are, independently, straight or branched C1-C6 alkyl or alkenyl groups, or aryl, aralkyl or alkaryl groups, or alkoxides of straight or branched C1-C6 alkyl or alkenyl groups, or aryl, aralkyl or alkaryl groups, or alkoxides wherein R2 and R3 together form a cyclic structure of at least five members. The siloxane-containing polysaccharide derivatives and polysaccharide graft polymers are useful in glass fiber forming size compositions, in paper making and in other applications.
