A filled engineering plastics is provided with improved impact strength by pretreating the filler to provide separate coating deposits of a coupling agent and an impact modifier for the plastics matrix - e.g. for nylon plastics, a kaolin filler coated with separate deposits of an amino functional silane coupling agent and a phenol or triethanolamine impact modifier has resulted in an improved strength without sacrificing tensile and elastic properties of the nylon.

A polymeric article and method for making a polymeric article, such as a catheter, are disclosed wherein the article is contacted with a swelling agent, such as a solvent, and a plasticizer to make the polymeric material softer and/or more pliable or flexible. The contacting may be carried our sequentially or simultaneously, using a solution comprising a plasticizer and a solvent.
An object of the present invention is to provide a curable composition made mainly of an organic polymer having a reactive silicon group, exhibits a good curability without using any organic tin compound substantially, and gives a cured product having a sufficient strength; and to provide a catalyst composition. The object is solved by a curable composition, comprising a polymer (A) having a silicon-containing group which can be crosslinked by forming a siloxane bond, and a fluoride salt compound (B).
