Branched polymers are prepared from at least (A) at least one monomer having an electron donor moiety, (B) at least one monomer having an electron acceptor moiety, and (C) at least one multifunctional branching agent comprising a urea moiety and at least two N-vinyl groups. The branched polymers are least 20% (by weight) soluble in a solvent for which the corresponding polymer of equal molecular weight made without said multifunctional branching agent is at least 20% (by weight) soluble. Due in part to the wide range of chemistries and solubility and rheological properties, the branched polymers find application in personal care, pharmaceutical/nutritional, and performance chemicals compositions.
分支聚合物由至少(A)至少一种具有电子给体基团的单体,(B)至少一种具有电子受体基团的单体和(C)至少一种多功能分支剂组成,该分支剂包含尿素基团和至少两个N-乙烯基团。这些分支聚合物在相应的等分子量聚合物不含多功能分支剂的溶剂中至少有20%(重量)的溶解度,由于其广泛的化学性质、溶解度和流变性质,这些分支聚合物在个人护理、制药/营养和性能化学成分中应用广泛。
