摘要： A laminated film and a process for its production with high polymers whose film inherently cannot be readily obtained by LB process comprises modifying the high polymers, and if required, further by cyclizing the product partially or wholly. The produced thin films have extremely excellent heat resistance, good chemical resistance and mechanical characteristics and its thickness is so small that it is generally hardly attainable, that is, less than 10,000 A, or if desired, super-thin films of 10 to 1000 A can be obtained.

摘要： A method of making a microporous sheet is provided which comprises the steps of melt blending crystallizable thermoplastic polymer with a compound which is miscible with the thermoplastic polymer at the polymer melting temperature but immiscible on cooling below the polymer melting temperature, forming a sheet of the melt blend, cooling the sheet to a temperature at which the compound becomes immiscible with the polymer to cause phase separation to occur between the thermoplastic polymer and the compound to provide a sheet comprising a first phase comprising particles of thermoplastic polymer in a second phase of said compound, orienting the film in at least one direction to provide a network of interconnected micropores throughout the sheet. The microporous sheet comprises about 30 to 80 parts by weight crystallizable thermoplastic polymer and correspondingly about 70 to 20 pans by weight of the compound. The oriented sheet has a microporous structure characterized by a multiplicity of spaced randomly dispersed, equiaxed, non-uniform shaped, non-porous particles of the thermoplastic polymer which are coated with the compound. Adjacent thermoplastic particles within the sheet are connected to each other by a plurality of fibrils consisting of the thermoplastic polymer. The fibrils radiate in three dimensions from each particle. The compound may be removed from the sheet. e.g., by solvent extraction.

摘要： Acrylic films having superior properties are produced by casting a solution comprising an organic solvent and a polymer system of one or more completely polymerized acryllc polymers onto a carrier, removing the solvent thereby forming the film on the carrier, and stripping the film from the carrier.

wherein: R, is hydrogen or methyl; and R 2 is striaght or branched alkyl of about 1-20 carbon atoms, preferably about 1-8 carbon atoms, more preferably 1-4 carbon atoms, and most preferably 1-2 carbon atoms. The polymers are homopolymers, mixed copolymers, and graft copolymers. They may be cross-linked. The polymers have the following properties:
Total Elongation (%) of about 120-250, preferably about 150-210, and more preferably about 170-190; Tear Resistance of about 4.5-12.5 g/mil (which is about 177-492 mg/micron), preferably 6-10 g/mil (which is about 236-394 mg/micron), and more preferably about 8-9 g/mil (which is about 315-354 mg/micron); Tensile Strength of about 4500-5000 Ibs/in 2 (about 317-387 kg/cm 2 ), preferably about 4800-5200 Ibsi/n 2 (about 338-366 kg/cm 2 ), and more preferably about 4900-5100 Ibs/in 2 (about 345-359 kg/cm 2 ). Molecular Weight (amu) of about 250,000-500,000, preferably about 300,000-400,000, and more preferably about 325,000-375,000; Acid Content (%) of about 0.0-5.0, preferably about 0.0-2.0, and more preferably about 0.0-0.9; Tucon hardness (Knoop No.) of about 6-12, preferably of about 7-11, and more preferably of about 8-10; and The polymer is substantially free of reactive groups, such as hydroxy groups. The acrylic film has Total Elongation, Tensile Strength, Tear Resistance, Acid Content and Tucon hardness in the aforesaid ranges, and is substantially free of reactive groups, such as hydroxy groups. The residual solvent in the film is (weight %) about 0-3, preferably about 0-2, and more preferably about 0.1-1.0. The film has dimensional stability (% shrinkage at about 130°C. for films of 0.5-5.0 mils, which is about 13-127 microns) of about 0-3, preferably of about 0-2, and more preferably of about 0.1-1.0. The thickness of the films is generally about 0.5-5.0 mils (which is about 13-127 microns), preferably about 0.75-3.0 mils (about 19-76 microns), and more preferably about 1.0-2.5 mils (which is about 25-63 microns).

摘要： There is presented a poly-p-phenyleneterephthalamide film which is excellent in tranparency, sufficiently oriented not only in the MD direction but also in the TD direction of the film, having high strength, elongation, modulus and dimensional stability in both longitudinal and lateral directions, and is also excellent in flatness. The film can be produced by forming an optically anisotropic dope comprising a poly-p-phenyleneterephthalamide having an ηinh of 2.5 di/g or higher and an inorganic strong acid type solvent into a film-shaped dope on a support surface, converting the dope into an optically isotropic dope by water absorption, coagulating the dope, then washing the coagulated product and drying while restricting it shrinkage.
