    Abstract: PROBLEM TO BE SOLVED: To obtain a hydrophilic polymer comprising specified structural units, which when applied to the skin, shows excellent moistening effect, touch, etc., and exhibits persistent moistening effect for a long time even when it is wetted with sweat or water or even after it is washed away with water and to obtain a humectant containing the same. SOLUTION: This polymer comprises structural units represented by the formula (wherein R and R are each a 1-10C alkyl which may be substituted with hydroxyl; and Y is a 1-10C divalent hydrocarbon group which may be substituted with hydroxyl) and having a weight-average molecular weight of 500-100,000. This is produced for example by the following process: glycidyl methacrylate is polymerized in the presence of a polymerization initiator in a solvent to obtain polyglycidyl methacrylate, and this is reacted with a secondary amine to obtain a polyaminoalkyl methacrylate, and, the product is reacted with an ω-halocarboxylate. The polymer may be a homopolymer or a copolymer.

    Abstract: PROBLEM TO BE SOLVED: To obtain the subject polymer having excellent moisture retaining properties in application to skin and hair, continuing its effects for many hours, having excellent touch, useful as a humectant for various cosmetics and detergent compositions, by including a specific structural unit. SOLUTION: This hydrophilic polymer comprises structural units of formula I and formula II [R and R are each H or methyl; R and R are each a (substituted) 1-10C alkyl; Y and Z are each NH or 0; Y is a (substituted) 1-10C bifunctional saturated hydrocarbon; (p) is 2-5; A is a 2-4C alkylene] and has 500-500,000 weight-average molecular weight.

    Abstract: PURPOSE:To obtain the title copolymer useful for a nonionic surface active agent by forming a specified chain by performing successive polymn. of a specified 2-oxazoline monomer. CONSTITUTION:After a monomer for the first-step polymn. is substantially completely polymerized, a monomer for the second-step polymn. belonging to a category different from that of said monomer is added thereto and polymerized to perform substantially completely the second-step polymn. Then another monomer which is the same as that for the first-step polymn. or belongs to the same group is added thereto to perform the third-step polymn. The title copolymer consisting of polymer blocks A and B each of which consists of repeating units of formula I or II (wherein R1 is H, CH3 or C2H5; R2 is a 4-5C hydrocarbon group) and having a chain of A-B-A or B-A-B, a wt. ratio of A/B of 5/95-95/5 and an MW of 500-50,000 is thereby obtd.
