Abstract: PURPOSE:To obtain a polyether-imide copolymer of excellent melt flow property, comprising units having a skeleton derived from a specified dihydric phenol and units having a skeleton derived from another dihydric. phenol. CONSTITUTION:This copolymer has repeating units of formula I, wherein the amount of Ar is 1-99wt.% and the amount of Ar' is 99-1wt.%. In formula I, Ar and Ar' are different from each other and are 6-44C bivalent organic groups, and R is a bivalent organic group selected from among a 6C or higher aromatic hydrocarbon group derived from an organic diamine or an organic diisocyanate, its halogenated derivative, an alkylene group, a cycloalkylene group, an alkylene group-terminated polyorganosiloxane and a group of formula II. In formula II, X is -O-, -S-, -CyH2y- or the like, y is an integer of 1-10, p is an integer of 0-10, and R5-R8 are each a hydrogen atom or a 1-5C alkyl group. Ar is a bivalent organic group of formula III (wherein R1-R4 are each a hydrogen atom, a halogen atom or a 1-5C linear or branched alkyl group). It is desirable that Ar' is a group of formula IV.

Abstract: PURPOSE:The titled elastomer that is composed of polyurethane containing, as soft segments, a specific diol and polyorganosiloxane, thus being suitable for use as a medical material such as for artificial heart, because it has a good balance between hydrophilic and hydrophobic properties and micro phase-separation structure. CONSTITUTION:The objective elastomer is a polyurethane or polyurethane urea, preferably containing 40-70wt% of the soft segments which is composed of (A) poly(oxy-2-methyl-1,3-propane)diol preferably with a number-average molecular weight of 400-2,000, preferably 20-50wt%, and (B) a polyorganosiloxane such as polymethylsiloxane, preferably with a number-average molecular weight of 200-3,000, preferably 5-30wt%. For example, a prepolymer having terminal NCO groups is prepared from components A and B, then a short-chain diol is used to effect chain extension to give the objective elastomer.

Abstract: PURPOSE: Plastic moldings are coated with partially hydrolyzed condensate of alkyltrialkoxysilane and the coating film is cured with far infrared rays to form uniform coating films of high slip properties and high scratch resistance on the surface of the moldings.
CONSTITUTION: A plastic molded product is coated with partially hydrolyzed condensate of alkyltrialkoxysilane such as methyltriethoxysilane on its surface. Then, the coated substrate is irradiated with far infrared rays of 3W50μm wave length from a far infrared rays radiation element with a total emission of 0.1W 1.5W/cm
2 from a distance of 1W100cm to the substrate to effect curing of the coating to form the objective coating film on the surface.
