    摘要: Difunctional oxazoline resins, which may be produced in a convenient one-step reaction from an arylalkylene dinitrile by reaction with an amino alcohol, are used in compositions with an additional curable compound or resin containing one or more carbon to carbon double bonds. The composition can be cured to a thermoset material, the curing mechanism occurring by the zwitterion polymerization of the bisoxazoline resin with the resin containing the one or more carbon to carbon double bonds. The reaction occurs without the need for curing initiators.(I)

    摘要: 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.

    摘要: Personal care compositions comprising a polymer-bound UV absorber are described that provide enhanced properties, including customizable UV spectrum protection, broad-spectrum UV spectrum protection, water resistance, and labile UV stabilization. The polymer comprises anhydride functionality, such as maleic anhydride or a derivative thereof, and the UV absorber contains at least one hydroxyl, primary amine, or secondary amine group.The personal care compositions may be used to treat and/or protect against burns, cancers, erythema, lentigo (“liver spots”), keratotic lesions, wrinkles, and cellular changes of the skin; and/or color changes, embrittlement, lack of luster, tangles, split ends, and/or unmanageability of the hair.
