PURPOSE:To obtain a hydrophilic, cationic oligomer comprising a low-MW polymer of a specific structure, a salt thereof with an org. or inorg. acid or a quaternization product thereof, which is excellent in surface activity, in pene trating into textile and paper and water resistance and is useful as a treating agent for these materials or as an emulsifier. CONSTITUTION:The title product is a cationic oligomer comprising a low-MW polymer having a mean MW of 500-10,000, a salt thereof with an org. or inorg. acid or a quaternization product thereof of formula I [where R<1> is 6-18C alkyl; R<2> and R<6> are each H, CH3; R<3> is a group of formulas II, III and IV; R<4> and R<5> are each H, 1-3C alkyl; A is a divalent org. group; B is H, a mono valent org. group; X is -O-, -NH-; Y is a group of formula V (where R<7> is 1-18 alkyl, 2-3C hydroxyalkyl), formula VI (where R<8> and R<9> are each H, 1-3C alkyl), formula VII and formula VIII; m is 2-100; n is 0.1-100]. The product has an excellent surface activity and is effective as an emulsifier for various oily substances and as an emulsifier for emulsion polymn. In addition, it is highly effective as a dye fixing agent for textile products and paper and in the treatment of softening agents, etc. The product is also excellent in water and light resistance. |
