摘要： PURPOSE:To decrease ionic impurities contained in a polymer without any loss of the polymer easily by dissolution, by contacting a polymer having carboxyl groups on both ends with water in the presence of a ketone which is a good solvent therefor and is miscible with water. CONSTITUTION:A polymer having carboxyl groups on both ends (e.g., 1,3- butadiene/acrylonitrile copolymer having carboxyl groups on both ends) and containing ionic impurities such as Na is contacted with water in the presence of a ketone (e.g., acetone) which is a good solvent therefor and is miscible with water. This mixture is settled or, desirably, centrifuged to separate a polymer solution layer from a water/solvent layer containing transferred ionic impurities. The solvent and the water are distilled from the polymer solution to obtain a polymer freed of ionic impurities. The obtained purified polymer can be suitably used as, e.g., a flexibility-inparting agent used in sealing a semiconductor with an epoxy resin.

摘要： PURPOSE: To obtain a durably porous film which does not show a deterioration of water permeability, if dried by adhering and causing a mixture of polyvinylacetal diethylaminoacetate and any other additive to be held by a part of a film with fine pores. CONSTITUTION: In a film comprising a thermoplastic resin with fine pores communicating from one side to the other provided at least, on the part of the film, a mixture of polyvinylacetal diethylaminoacetate and at least, one type of any other additive is caused to adhere to and to be held by, at least, a part of the film with fine pores to donate hydrophilic effects. In addition, the themoplastic resin is, at least, one type of material selected from among hydrophobic themoplastic resins, a copolymer of two or more different types of the selected resin or a blend of two or more different types of the selected resin. The additive is a nonionic surfactant or a hydrophilic polymer.

摘要： PURPOSE:To produce a reinforced polybutadiene excellent in mechanical properties and heat resistance comprising two phases of n-hexane solubles and insolubles by subjecting 1,3-butadiene to cis-1,4 polymerization in the presence of a specified polymerization catalyst and then subjecting 1,3-butadiene to 1, 2 polymerization in the presence of another specified polymerization catalyst.

摘要： PURPOSE: To make it possible to donate durably hydrophilic effects by adhering and causing polyvinyl acetal diethylaminoacetate to be held by a film comprising a thermoplastic resin with fine pores communicating from one side to the other. CONSTITUTION: A soaking liquid is prepared by dissolving polyvinyl acetal diethylaminoacetate in either of alcohol, ketone or aromatic solvent, or a mixture of these solvents, or the water-containing solvent(s) thereof, preferably, in either one or the blend of two or more of methyl alcohol, ethyl alcohol or acetone, or either or these blends containing water. Next, a porous film consisting of either one material selected from among hydrophobic thermoplastic resins such as polyethylene, polypropylene or polyimide, a copolymer of two different types or more selected from among said resins, or a blend of two or more different types selected from among said resins, is soaked in the liquid. Thus even the fine through pores of the film are adequately impregnated with the liquid and are dried so that the solvent is removed. This hydrophilic polyolefin porous film does not show a deterioration of the water permeability, even if the porous film becomes dry after filtration.
