Abstract

A polymer consisting mainly of structural units represented by the general formula (1), wherein the total molar amount of terminal aldehyde groups and acetal groups is 0.6 mol % or smaller based on the total molar amount of the structural units represented by the general formula (1). —[—(—CHR1—)n—CX1R2—CX2R3-]— (1) (In the formula, n is an integer of 2 to 10; X1 and X2 each represents —H, —OH, or a functional group capable of being converted into —OH, provided that at least one of X1 and X2 is hydroxy or a functional group capable of being converted into hydroxy; and R1, R2, and R3 each represents —H or C1-5 alkyl, aryl, aralkyl, or heteroaryl and the two or more R1's may be different.)

Claims7

Dependent claims

A polymer comprising mainly structural units represented by the following general formula (1):

(wherein, n stands for an integer of from 2 to 10;
X1 and X2 each represents a hydrogen atom, a hydroxy group or a functional group that can be converted into a hydroxy group, provided that at least one of X1 and X2 represents a hydroxy group or a functional group that can be converted into a hydroxy group;
R1, R2 and R3 each represents a hydrogen atom, an alkyl group having from 1 to 5 carbon atoms, an aryl group, an aralkyl group or a heteroaryl group, provided that plural R1s may be the same or different), wherein the total molar amount of the terminal aldehyde group and acetal group contained in the polymer is 0.6 mol % or smaller relative to the total molar amount of the structural units represented by the formula (1).

Dependencies are inferred from the claim text.
