Abstract:
A polymeric compound having a weight-average molecular weight of 1,000 to 500,000 and having one or more hydroxyl and/or carboxyl groups in the molecule, part or all of the hydrogen atoms of the hydroxyl groups and/or the hydrogen atoms of the carboxyl groups being replaced by groups of the following general formula (1): ##STR48## wherein R.sup.1 and R.sup.2 are each a hydrogen atom or a straight-chain, branched or cyclic alkyl group of 1 to 6 carbon atoms;R.sup.3 is a (n+1)-valent hydrocarbon group of 1 to 18 carbon atoms which may have one or more heteroatoms;R.sup.1 and R.sup.2, R.sup.1 and R.sup.3, R.sup.2 and R.sup.3, or R.sup.1, R.sup.2 and R.sup.3 may form a ring, and in cases of ring formation, R.sup.1 and R.sup.2 are each a divalent or trivalent hydrocarbon group of 1 to 6 carbon atoms, and R.sup.3 is a (n+2)- or (n+3)-valent hydrocarbon group of 1 to 18 carbon atoms which may have a heteroatom;R.sup.4 is a monovalent hydrocarbon or alkoxy group of 1 to 18 carbon atoms which may have one or more heteroatoms; andn is an integer of 1 to 6.
