摘要:
An adhesion promoter containing silane, and carbamate, thiocarbamate or urea functionality, and electron donor or electron acceptor functionality, displays low volatility.
摘要:
Compounds with both vinyl ether and carbamate, thiocarbamate or urea functionality are suitable for use in microelectronics applications and show enhanced adhesive strength compared to compounds that do not contain carbamate, thiocarbamate or urea functionality.
摘要:
The present invention relates to a polymer comprising an N-vinyl amide monomer and a dual functional monomer. In the case where the dual functional monomer incorporates a glycidyl acrylate, a third polymerizable monomer is also included. The polymer can be varied in charge.
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.
摘要:
Carbamate and thiocarbamate compounds are described that comprise a polymerizable moiety and one or more free hydroxyl and/or thiol groups. Polymers may be obtained by polymerizing these carbamate and/or thiocarbamate compounds. The carbamate and thiocarbamate compounds, as well as the polymers they produce may be formulated into adhesive, agricultural, biocide, cleaning, coating, encapsulation, membrane, oilfield, performance chemical, and personal care compositions.
摘要:
Disclosed are novel ultraviolet-absorbing compounds produced by two embodiments. By a first embodiment, the ultraviolet-absorbing compound is derived from at a first reactant being a UV absorber comprising a carbon-nitrogen triple bond and a second reactant having amine functionality. By a second embodiment, the ultraviolet-absorbing compound is derived from a first reactant being a UV absorber comprising amine functionality and a second reactant comprising a carbon-nitrogen triple bond. In both embodiments of the invention, the second reactant may be a small molecule, a monomer, a macromolecule, a biomolecule, or a polymer.The invention's ultraviolet-absorbing compounds are directed toward formulations and applications that serve to protect against UV radiation in any art. Exemplary uses of the ultraviolet-absorbing compounds are in adhesive, agriculture, cleaning/polishing, coating, containers, encapsulation, fragrances, imaging, hoses/tubing, household/industrial/institutional, medical, membrane, molded parts, oilfield, packaging, personal care, personal protective equipment, pharmaceutical, printing, veterinary, and wood-care applications. Highly preferred uses of the ultraviolet-absorbing compounds are in personal care and performance chemicals. wherein R═
