Abstract: PURPOSE: To obtain a polyether polymer excellent in hue and useful as e.g. a starting material for cosmetics by bringing a polyether polymer derived from a polyepihalohydrin into contact with a specified compound. CONSTITUTION: Nitrogenous groups are introduced into a polyepihalohydrin comprising repeating units of formula I (wherein V is a halogen; and m has an average of 10-1,500) to obtain a polyether polymer comprising repeating units represented by formula II [wherein Y is a group of formula III or IV (wherein R and R are each a 1-20C (hydroxy) alkyl or alkenyl; and Z is a 1-20C (hydroxy) alkylene)] and bringing this polymer into contact with a boron hydride compound. The decolorization reaction of the polymer with the boron hydride compound is carried out in a solution. The solvents used are desriably alcohols and water, particularly desirably water. The boron hydride compound is particularly desirably sodium boron hydride.

Abstract: PURPOSE:To obtain the title surfactant having excellent properties as a cationic surfactant and mildly acting on the skin or the like by reacting a specified polyamine compound with a poly(N-acylalkyleneimine) obtained by a specified preparative process. CONSTITUTION:A polyamine compound having at least two basic nitrogen atoms in the molecule desirably a compound of formula I [wherein R2, R3, R5 and R6 are each H, 1-3C (un)saturated hydrocarbyl, 1-3 C hydroxyalkyl; R2 and R3, R4 or R5 may be combined with each other to form a ring; R4 is a bivalent group comprising an (un)saturated hydrocarbon which may contain O, S, N or halogen; and k is 1-5], is reacted with a poly(M-acylalkyleneimine) obtained by polymerizing a cyclic imino ether compound of formula II (wherein R1 is H, 1-22 C alkyl, cycloalkyl, aralkyl or aryl; and n is 2 or 3) through ring opening to obtain a cationic surfactant. The obtained surfactant excels not only in the characteristic ability to soften the fiber or the hair but also in the prevention of skin sensitization, antistatic properties, non-irritativeness to the skin and is therefore highly safe.

Abstract: PURPOSE:To obtain the title copolymer useful for a nonionic surface active agent by forming a specified structural unit by performing ring-opening 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. is added thereto and polymerized to perform substantially completely the second-step polymn. Then another monomer for the third-step polymn. is added thereto to perform the third-step polymn. The title copolymer consisting of two kinds of polymer blocks A and B wherein the block A consists of two or more repeating units of formula I (wherein R1 is H or a 1-3C alkyl) and the block B consists of repeating units of formula II (wherein R2 is a 6-22C alkyl, aralkyl or aryl) and having an MW of 500-50,000 is thereby obtd.

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 different category 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 of the first-step polymn. or belongs to the same category 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, a 1-3 alkyl; R2 is a 6-22C alkyl, aralkyl or aryl) and having a chain of A-B-A or B-A-B and an MW of 500-50,000 is thereby obtd.
