TRANSPARENTE COPOLYAMIDE UND IHRE VERWENDUNG

摘要

Transparent copolyamides derived from alkyl derivatives of bis(4-aminocyclohexyl)methane and, optionally, other diamines with isophthalic acid and, optionally terphthalic acid or aliphatic dicarboxylic acids and further polyamide forming components having 6 or more carbon atoms, using bis(4-amino-3- methyl-5-ethylcyclohexyl)methane having a selected mixture of isomers which preferably contains trans/trans and/or cis/trans isomers. The transparent copolyamides are especially suitable for lightwave guide cladding and processing by injection moulding to give moulded bodies.
