Title:
POLYMER AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JP3413898
Kind Code:
B2
Abstract:
PURPOSE: To obtain a polymer which has thermally reversible solubility in water, that is, which is soluble in a low-temp. region and insoluble in a high- temp. region, and which is excellent in safety and temp. sensitivity by constituting it of specific repeating units.
CONSTITUTION: This polymer is made up of 100-90mol% repeating units represented by formula I (wherein R is a 2-4C alkyl) and 0-10mol% repeating units represented by formula II. This polymer is obtained preferably by reacting polyvinylamine and/or a salt thereof (e.g. polyvinylamine hydrochloride) with a carboxylic acid (halide) (e.g. isobutyryl chloride).
