    Abstract: PURPOSE:To obtain the title composition which is excellent in mechanical strengths and representation and can give lows-strain molding, by mixing a polyamide obtained to polymerizing a lactam in the presence of an alkali with at least one reinforcement selected from among specified wollastonite, glass flakes and milled glass. CONSTITUTION:A definite amount of a lactam (A) such as anhydrous caprolactam is uniformly and easily mixed with a definite amount of one to three reinforcements (B) selected from among wollastonite (a) of a content of particles of a diameter

    Abstract: PURPOSE:To obtain a polyamide excellent in weathering resistance and suitable for use in automobile parts, etc., by polymerizing a lactam in the presence of a bisphenol compound and a hindered amine compound by the action of an alkali catalyst and a promotor. CONSTITUTION:A lactam such as gamma-butyrolactam or delta-valerolactam is mixed with a bisphenol compound [e.g., 4,4'-butylidenebis (6-tert-butyl-m-cresol or 4,4'-thiobis (3-methyl-6-tert-butylephenol)], a hindered amine compound [e.g., bis (2,2,6,6-tetramethyl-4-piperidyl) sebacate], an alkali catalyst (e.g., sodium hydroxide or sodium methylate) and a promotor (e.g., hexamethylene diisocyanate). This mixture is polymerized to obtain the purpose polyamide.

    Abstract: PROBLEM TO BE SOLVED: To obtain the subject film having excellent slipperiness under high- humidity condition while keeping the transparency and surface gloss of the film by forming protrusions having a specific size on a polyamide film surface at a specific density and hydrophobicizing the film. SOLUTION: This polyamide film has a surface roughness characterized by the presence of 6-30/mm of protrusions having a height of >=0.06μm from the center line measured by a surface-roughness tester, a static contact angle of >=64 deg. with water at 23 deg.C, a haze value of 110. The film can be produced by compounding a polyamide resin with a surface- roughening substance, especially inorganic fine powder, concretely gel-type silica, etc., and a surface-hydrophobicizing substance, especially a long-chain aliphatic bisamide compound such as N,N'-ethylenebisbehenamide, forming the composition in the form of a film and drawing the film at an areal draw ratio of >=3.

    Abstract: PROBLEM TO BE SOLVED: To provide a polyamide having excellent drawability and especially suitable for successive biaxial drawing. SOLUTION: The objective polyamide contains a unit composed of a lactam and/or an aminocarboxylic acid, a unit composed of a dicarboxylic acid and a unit composed of a diamine containing norbornanediamine. Concretely, the polyamide contains 50-99.8 mol% lactam and/or aminocarboxylic acid, 0.1-25 mol% dicarboxylic acid and 0.1-25 mol% diamine. Norbornanediamine accounts for 10-100 mol% of the diamine.

    Abstract: PROBLEM TO BE SOLVED: To obtain a polyamide excellent in stretchability especially successive biaxial stretchability. SOLUTION: This polyamide comprises a diamine and a dicarboxylic acid including a 6-22C branched and saturated carboxylic acid as essential components. The preferable composition is 50-99.95 mol% lactam and/or aminocarboxylic acid, 0.025-25 mol% diamine and 0.025-25 mol% dicarboxylic acid wherein 5-100 mol% of the dicarboxylic acid is a 6-22C branched and saturated carboxylic acid. As the 6-22C branched and saturated carboxylic acid, 1,6-decanedicarboxylic acid is preferable.
