摘要： A moisture-curing polyurethane composition including: at least one isocyanate-functional polymer with a content of monomeric isophorone diisocyanate of below 0.5 weight-%, obtained from the reaction of isophorone diisocyanate and at least one polyol, and at least one aldimine of formula (I). The composition has a low toxicity, good shelf life stability and cures quickly to an elastic material of low surface tack and good mechanical properties, particularly in terms of high tensile strength and modulus of elasticity at high elongation. It enables coatings, sealants and adhesives with excellent stability under outdoor weathering conditions and high UV load. The aldimine of formula (I) allows to overcome the drawbacks caused by the removal of most of the monomeric isophorone diisocyanate in terms of cure speed, surface tackiness and final strength of such compositions.

摘要： A curable composition containing more than 80% by weight of a blend of benzoxazines, wherein the blend includes (A) one or more multifunctional benzoxazines and (B) a liquid, non-halogenated monofunctional benzoxazine. This composition has been found to be stable at high temperatures, e.g. 180° C.-250° C., and suitable for making composite materials using conventional techniques such as prepregging and liquid resin infusion.

摘要： A radiation-sensitive resin composition contains: a polymer having a first structural unit represented by formula (1), and a second structural unit represented by formula (2) and having an acid-labile group. A first acid, to be generated from the first acid generating agent, disassociates the acid labile group in the polymer upon heating under a condition involving a temperature of no less than 80° C. and no greater than 140° C. for a time period of 1 minute, and the second acid, to be generated from the second acid generating agent, does not substantially disassociate the acid-labile group under the condition. The polymer is synthesized by RAFT, ATRP, or NMP, and a RAFT agent is at least one selected from the group consisting of a mercaptocarboxylic acid ester, a disulfide, a dithioester, a xanthate, a dithiocarbamate, and a trithiocarbonate.

摘要： The present invention concerns the curing and hardening of liquids comprising unsaturated resins, a peroxide and a chelant capable of chelating at least one transition metal ion through three, four, or five nitrogen atoms, which chelants may each optionally be complexed with one or two transition metal ions, typically iron or manganese ions. The invention also provides methods and formulations for making associated compositions, compositions resultant from the curing of such liquids and associated kits comprising two or more compositions physically separated from one another, which may be used to provide curable liquids when mixed.
