Patent ID: 7326765

Claim:
A melamine ring-containing co-polymer of formula (I) wherein m is an integer of 1 to 100; R 1 is independently selected from the group consisting of alkyl groups having one to twenty carbon atoms; R 2 is independently selected from the group consisting of an oxygen atom and a sulfur atom; R 3 is independently selected from the group consisting of an alkyl group, an allyl group, an alkynyl group, an aryl group, and a phenyl group, having one to seventy carbon atoms; R 4 is independently selected from the group consisting of —C p H 2p OH; —C p H 2p−1 OH; —C p H 2p−2 OH, wherein p is an integer of one to seven; a hydrogen atom; a carboxyl group, an alkyl group; an allyl group; and an alkynyl group; R 5 is independently selected from the group consisting of an alkyl group, an alkyl group containing at least one ether linkage, and the group represented by the formula (III): wherein R 7 is independently a C 10 -C 40 branched or unbranched, substituted or unsubstituted alkyl, allyl, or alkynyl group, and; n is an integer of one to thirty; wherein the melamine ring-containing co-polymer is the reaction product of at least one melamine base resin and at least one reactant compound, wherein the at least one reactant compound comprises a cashew nut shell liquid and has at least one functional group selected from a carboxyl group, a hydroxyl group, a thiol group and combinations thereof.
