    • A novel moisture-curable polymer useful as a pressure sensitive adhesive, a paint, a sealant, etc. obtained by polymerizing a polymerizable monomer in the presence of an organic polymer having at least one reactive silicon-containing functional group in the molecule on the average. A pressure sensitive adhesive composition having excellent adhesive property as well as excellent initial tackiness, heat resistance, workability and weather resistance comprising a polymer obtained by polymerizing a polymerizable monomer in the presence of (A) an organic polymer having at least one reactive silicon functional group in the molecule on the average and/or (B) an organic polymer having at least one olefin group in the molecule on the average. The composition is also useful as a sealant, a coating material, a packing, an electric insulation, a corrosionproof, a masking and a surface-protection.

    • A process for preparing a polyalkylene oxide having allyl end-group, by subjecting an alkylene oxide monomer to addition polymerization in the presence of potassium hydroxide in an amount of 2 to 30% by mole to the monomer at a temperature of 20.degree. to 100.degree.C., and reacting the polymerized alkylene oxide with an allyl halide compound, or by subjecting the monomer to addition polymerization in the presence of potassium hydroxide, reacting the polymerized alkylene oxide with an organic polyhalide and then reacting with an allyl halide compound. Potassium hydroxide is preferably employed in combination with the specific initiator. There can be prepared polyalkylene oxide of which all of the chain ends are substantially allyl group.
    • 一种制备具有烯丙基端基的聚环氧烷烃的方法,该方法是在二氧化碳单体在氢氧化钾存在下,在20〜100℃的温度下,以2〜30摩尔%的量进行加成聚合。 使聚合的烯化氧与烯丙基卤化物反应,或在氢氧化钾存在下使单体进行加成聚合,使聚合的烯化氧与有机多卤化物反应,然后与烯丙基卤化物反应。 氢氧化钾优选与特定引发剂组合使用。 可以制备其全部链端基本上是烯丙基的聚环氧烷。
