Title:
透明なポリアミド−イミド
Document Type and Number:
Japanese Patent JP5757973
Kind Code:
B2
Abstract:
A transparent polyamide-imide (P1) based on at least one different imido-dicarboxylic acid (AB) or its derivative, and cycloaliphatic diamine (C1) comprising 6-24C, is new. A transparent polyamide-imide (P1) based on at least one different imido-dicarboxylic acid (AB) or its derivative, and cycloaliphatic diamine (C1) comprising 6-24C, where the AB or its derivative is selected from compounds of formulae (I)-(III), is new. Where the transparent polyamide-imide is free from building blocks in which the C1 are, with its at least one amino-group, forming the imido-element of imido-aminocarboxylic acids corresponding to the AB and in which the C1 are replacing the structural element N-ASL-COR', where the transparent polyamide-imide is free from aromatic diamines. ASL : (CH 2) 5 - 1 1, phenylene, (ylomethyl)phenyl, bis(ylomethyl)benzene, cyclohexanediyl, (ylomethyl)cyclohexyl, bis(ylomethyl)cyclohexane, cyclopentanediyl, (ylomethyl)cyclopentyl, or bis(ylomethyl)cyclopentane; R' : OH, O-alkyl, O-aryl, Cl, NH-ASL-COOH, Br, O-(CO)-alkyl, or O-(CO)-aryl; R 1H, methyl, ethyl, propyl. Provided that the ring can be substituted once or twice, and, with double substitution of the ring, the two substituents can be selected from the group, but may be different. Independent claims are included for the following: (1) molding compound (M1) based on the polyamide-imide (P1) having composition comprising 30-100 wt.% the polyamide-imide (P1), 0-70 wt.% or 20-60 wt.% reinforcing agents and/or fillers (F2), and 0-50 wt.% additives and/or further polymers (F3), different from the polyamide-imide; (2) preparation of the polyamide-imide (P1).
