Patent ID: 7520982

Claim:
A polymer in which a particle-type polymer with a reactive end-substituted group is linked to a cucurbituril derivative of Formula 1 below by a covalent bond: wherein n is an integer of 4 to 20, and each R 1 is independently a substituted or unsubstituted alkenyloxy group of C 2 -C 20 with an unsaturated bond end, a carboxyalkylsulfanyloxy group with a substituted or unsubstituted alkyl moiety of C 2 -C 20 , a carboxyalkyloxy group with a substituted or unsubstituted alkyl moiety of C 2 -C 8 , an aminoalkyloxy group with a substituted or unsubstituted alkyl moiety of C 1 -C 8 , a hydroxyalkyloxy group with a substituted or unsubstituted alkyl moiety of C 1 -C 8 , or an epoxyalkyloxy group with a substituted or unsubstituted alkyl moiety of C 2 -C 8 .
