摘要：
A polymeric material having low tack which has a straight or branched chaincarbon-carbon polymer backbone and a multiplicity of side chains attached tothe backbone wherein the side chains, which are attached directly to carbonatoms of the polymer backbone, have the formula (I) or have the formula (II)wherein R1 is H, -C(O)OR4 or -C(O)Q and R2 is -C(O)OR4 or -C(O)Q provided thatat least one of R1 and R2 is the group -C(O)Q； R3 is H or -CH3 ； R4 is H or analkyl group having from 1 to 6 carbon atoms； Q is a group having the formula -O-(YO)b-(ZO)c-R5, wherein each of Y and Z is, independently, an alkylene grouphaving from 2 to 4 carbon atoms and R5 is H or an alkyl group having from 1 to4 carbon atoms； a is 3 or 4 and each of b and c is, independently, 0 or aninteger of from 1 to 125 provided that the sum b + c has a value in the rangeof from 10 to 250, preferably from 10 to 120. The polymeric material may beused to replace at least part of a water-~insoluble gum base in a chewing gumcomposition to give a composition exhibiting reduced adhesion to surfaces.
