Abstract
The monomer of the present invention is represented by the following Formula 1: 1 wherein X, R1 to R3, and m are as defined in the disclosure. The monomer is structurally characterized by the presence of a tertiary hydroxyl group and a vinyl-polymerizable group X and the absence of an ester linkage derived from a tertiary hydroxyl group. Polymers produced by the polymerization of the monomer and an optional comonomer have a moderated reactivity and hydrophilicity.
Claims11
A polymer having a tertiary hydroxyl group, which is produced by polymerizing a first monomer component of at least one vinyl-polymerizable monomer and a second monomer component of at least one vinyl comonomer other than the at least one vinyl-polymerizable monomer, the first monomer component being 5 to 100 mol % and the second monomer component being 0 to 95 mol % each being based on a total of the first monomer component and the second monomer component, wherein a number average molecular weight calibrated by polystyrene standard is 1000 to 100,000, a hydroxyl value is 50 to 300 mgKOH/g, and a first monomer component is represented by the following Formula 1:
- 5
- wherein X is a vinyl-polymerizable functional group;
- R1 and R2 may be the same or different and each is an alkyl group having 1 to 4 carbon atoms;
- R3 is methyl or hydrogen;
- and m is an integer of 1 to 3, with the proviso that two or three R3 groups when m is 2 or 3 are the same or different from each other.
