CONSTITUTION: The vinyl polymer having OR
1 , CO
2 H and CO
2 R
2 (R
1 and R
2 are both hydrocarbon groups and the sum of C number of both is 3 or 4) at its side chains is used as the major component. Here, R
1 and R
2 are CH
3 , C
2 H
5 , normal propyl, isopropyl, etc. and when both are CH
3 , these are excluded. This polymer is synthesized by causing, e.g., the copolymer of vinyl alkyl ether and maleic anhydride to react with alcohol.
