Japanese Patent JP4803774

B2

Copolymers made of lower olefins and vinyl esters contain (a) 85-97 mol.% bivalent structural units of formula -CH2CR1R2- (1), where R1, R2 = H or CH3; and (b) at least 3 mol.% bivalent structural units of formula -CH2CH(OCOR3)- (2), where R3 = saturated branched 6-16C alkyl having a tertiary C atom, and R3 with the tertiary C atom is bound to the carboxyl function. Preferably the copolymers contain up to 15 (especially 5-10) mol.% of structural units (2), and have melt viscosities at 140 degrees C of 20-10000 (especially 30-5000, more especially 50-2000) mPas. The copolymers preferably contain up to 3 mol.% vinyl acetate or up to 5 mol.% further comonomers, preferably vinyl ester, vinyl ether, acrylic acid alkyl ester or up to 5C higher olefins, preferably hexene, 4-methyl pentene, octene or diisobutylene.
