The unsaturation of a hydroxyl-containing compound can be reduced by reaction with a nitrile oxide compound such as tetramethyl terephthalonitrile, N,N'-dioxide. The reaction of a nitrile oxide with terminal unsaturation associated with the preparation of a polyol from propylene oxide reduces the monol content of the polyol composition.
The invention is a laminate structure comprising two or more layers of one or both of a) a polymeric layer containing olefinic unsaturation; and b) a polymeric layer having active hydrogen atoms; wherein, c) an adhesive layer is located between the layers derived from one or more compounds having one or more nitrile oxide moieties; wherein a portion of the nitrile oxide moieties, or derivatives thereof, is reacted with olefinic unsaturation of layer a), the active hydrogen atoms of layer b or both.
Natural rubber and/or synthetic polyisoprene film products having enhanced tear strength and tensile strength crosslinked with a one polynitrile oxide, intended for direct or indirect contact with living tissue or fluids to be placed in living organisms.
