    摘要: The present invention relates to dual curing compositions, which cure with moisture and photo radiation, such as UV light, and methods for preparing and using same. In particular, the compositions of the present invention contain a polyether or polyester backbone, photocurable portion(s) and moisture curable portion(s). The photo curable portion is a urethane or carbamate linkage terminated with a (meth)acryloxyalkyl group. The moisture curable portion is either: (1) a portion terminated with a polyalkoxysilyl group; or (2) a portion having a urea linkage terminated with an alkylpolyalkoxysilyl group.

    摘要: The present invention provides moisture-curable polymeric compositions, overcoming disadvantages normally associated with moisture-curable polymeric compositions, a process for their preparation, and methods of use thereof. The process included in the present invention ensures full end-capping. Furthermore, the present invention makes use of diisocyanates to chain-extend polyether polyols to a desired length. This allows the process of the present invention to accommodate a wide range of polyether polyols in the synthesis of the compounds of the invention. Additionally, the process of the present invention reduces the level of unreacted isocyanate to an acceptable level of approximately 0.1 wt %.

    摘要: An alkoxylate adduct of a polyol. The polyol is an amorphous diol having a melting point above about 100° C. The alkoxylate is propylene oxide, butylene oxide, a mixture of propylene oxide and butylene oxide or a mixture of one or both of propylene oxide and butylene oxide with up to 50 mole % of ethylene oxide. The first polyol has an average of from about 1 to about 5 units of alkoxylate per mole of said amorphous diol. The adduct is useful in preparing urethane (meth)acrylate capped resins and compositions thereof. Resins prepared from such adducts have better manufacturing and solubility properties while retaining similar physical properties to resins prepared from the unadducted diol. The adduct may be for instance a propoxylate of hydrogenated bisphenol A having an average of from 1.5 to 3.5 moles of PO per mole of hydrogenated bisphenol A.
