摘要： PURPOSE:To enable the film forming by extruding adhering resin to be achieved by means of coextruding the adhering resin and polyolefin resin. CONSTITUTION:For instance, an inflation film manufacturing device is used, and a tubular fused sheet is manufactured by coextrusion, while feeding adhering resin to the extrusion machine A for an outer layer, and feeding polyolefin resin (e.g. PE, PP, etc.) to the extrusion machine B for an inner layer. Next, said sheet is taken up, while cooling and blowing up it and applying draft to it by a nip roll 5. Thus, the adhering resin film having generally 0.01-2mm. thickness, may be obtained. Further, this process is especially effective, when the composition containing polyvinyl acetal resin and plasticizer are used as the adhering resin.

摘要： PURPOSE:To manufacture fine-grain solid TiCl3 useful as an alpha-olefin polymerization catalyst component by subjecting liquid TiCl3 to deposition treatment in the presence of a specified ester cpd. CONSTITUTION:To liquid TiCl3 obtd. by reducing TiCl4 with an org. aluminum cpd. in the presence of an ether of formula R -O-R (where R and R are same or different hydrocarbon residue) and a solvent is added an ester cpd. of the formula (where R and R are hydrocarbon residue and the total of the carbon no. of R and that of R is 10 or more) in an ester cpd. to deposited TiCl3 molar ratio of 0.005- 0.50. After adding a (halogenated) hydrocarbon solvent as required, they are heated to 20-150 deg.C to deposit purple fine-grain solid TiCl3. This solid TiCl3 is then recovered and washed with a hydrocarbon solvent to remove the unreacted TiCl4.

摘要： PURPOSE:To obtain a resistance layer film enhanced in elongation at breakage and hard to cut at the time of processing or at the time of use as a ribbon by respectively containing a specific amount of a polycarbonate resin, a specific amount of carbon black and an elastomer whose amount is specific with respect to polycarbonate. CONSTITUTION:A resistance layer film for a current supply thermal recording essentially contains 50-85wt.% of a polycarbonate resin, 15-50wt.% of carbon black and a polystyrene/polyolefin block copolymer type elastomer whose amount is 0.1-30 pts.wt. per 100 pts.wt. of the polycarbonate resin and obtained by uniformly mixing carbon black, the polycarbonate resin and the elastomer and forming the resulting mixture into a film having a thickness of 30mum or less pref. by a solution casting method. In the solution casting method, carbon black and the elastomer are added to an org. solvent having the resin dissolved therein and mixed sufficiently to prepare a viscous solution in which carbon black is dispersed and this solution is applied to a support to be dried by evaporating the solvent and subsequently released from the support to obtain the resistance layer film.

摘要： PURPOSE:To obtain a resistance layer film for electrothermal recording hard to break by constituting said film of a polycarbonate resin, carbon black and silicone liquid at room temp. in a specific ratio. CONSTITUTION:A polycarbonate resin is prepared by reacting a bisphenol compound with carbonic ester and used in an amount of 50-80% by wt. of the sum total amount with carbon black. Carbon black to be used is composed of either one of conductive carbon black and usual carbon black or a mixture thereof and compounded in an amount of 15-50wt.%. As the silicone liquid at room temp., dimethylpolysiloxane or alkyl modified silicone is used and the addition amount thereof is set to 0.01-5pts.wt. per 100pts.wt. of the polycarbonate resin. After carbon black and the polycarbonate resin are uniformly mixed, the resulting mixture is formed into a film and, when a current supply thermal transfer recording material composed of three layers is prepared, a membrane of a good conductive substance is formed on a resistance layer film and, thereafter, an ink layer is applied thereto. As a result, the electrothermal transfer recording material hard to break is obtained.
