Title:
COMPOSITION CONTAINING POLYMER OF STAR-STRUCTURE, THE POLYMER AND USE THEREOF
Document Type and Number:
Japanese Patent JP3383261
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a polymer that can retain a suitable hair style, as easy untangling properties of the hair is maintained, and is useful as a hair styling composition or the like by allowing this polymer to include a specific star-like structure and to, satisfy specific conditions.
SOLUTION: This polymer includes star-like structure represented by the formula: A-[(M1)p1-(M2)p2...(Mi)pj]n {A is a multifunctional center that is n- functional; [(M1)p1-(M2)p2...(Mi)pj]n is so called one branching chain and means the polymer chain formed by polymerization of a monomer Mi with a polymerization index (degree) of pj and is covalently grafted to A; n, i, pj are each ≥2} and contains one or more kinds of monomers Mi so that the following conditions may be satisfied: the polymer corresponding to the monomer Mi has a Tg of ≥10°C, preferably ≥15°C, more preferably ≥20°C, and the content of the monomer Mi is set to about 55-95 wt.%, preferably 60-93 wt.%, more preferably 65-90 wt.% based on the final polymer.
