Document Type and Number:
Japanese Patent JP4416073
Kind Code:
B2
Abstract:
A transparent polyamide molding composition has a melt enthalpy of 0-12 J/g and contains a diamine mixture of (bis-(4-amino-cyclohexyl)-methane) and (bis-(4-amino-3-methyl-cyclohexyl)-methane. A transparent polyamide molding composition (I) has a melt enthalpy of 0-12 J/g and the polyamide is prepared from: (a) 100 mol.% of a diamine mixture with 10-70 mol.% PACM (bis-(4-amino-cyclohexyl)-methane) with less than 50 wt.% trans, trans-isomers and 30-90 mol.% (bis-(4-amino-3-methyl-cyclohexyl)-methane (MACM) and optionally replaced by 0-10 mol.% of other 6-12 C aliphatic diamines, cycloaliphatic, optionally alkyl subsituted, branched aliphatic diamines and/or 3-12C multiamines and; (b) 100 mol. % 8-14C aliphatic dicarboxylic acids, optionally replaced by 0-10 mol.% of other aromatic or cycloaliphatic 8-16C dicarboxylic acids, preferably isophthalic acid, terephthalic acid, naphthalene dicarboxylic acid and/or cyclohexane dicarboxylic acid whereby 0-10 mol.% of the other long chain aliphatic diamines and 0-10 mol.% of the other long chain aliphatic dicarboxylic acids are optionally added as 0-20 mol.% 6-12 C omega-aminocarboxylic acids or 6-12C lactams. Independent claims are included for: (1) a process for the production of polyamide molding compositions (I) by polycondensation by known processes in known pressure vessels having a pressure phase at 260-310 degreesC, a decompression phase at 260-310 degreesC , a degassing phase at 260-310 degreesC, whereby the composition (I) is removed in strands, cooled in a water bath at 5-80 degreesC and granulated followed by drying for 12 hours at 80 degreesC to a water content of less than 0.06% and; (2) a process for the production of spectacle lenses, prepared from the molding composition (I) and colored by dipping in an alcohol, ester, ketone or water-containing pigment solution, softening by dipping in acetone and coating with conventional hard coat lacquers that contain UV-protective agents, pigments, antistatic agents, toughening agents or other functional agents and curing thermally or by UV; (3) a process for the production of spectacle lenses by vapor coating the molding composition (I) with metals or treatment in another conventional form; (4) a process for the production of spectacle lenses by spraying or laminating the molding composition (I) with corresponding modified polarization films or protective films; (5) spectacle lenses and frames made from the composition (I); (6) a process for the production of molded parts prepared from the molding compositions (I), optionally with other compatible molded parts by bonding together by ultrasound, hot wire welding , friction welding, rotation welding or laser welding at 800-2000 nm following treatment with a laser active dye.
