Abstract
PURPOSE: To obtain a copolyamide as a high-molecular heat-sensitive substance, by copolymerizing a specified amount of a polyamide polymer component having at least one of the repeating units represented by specified formulasIand II with a polybutadiene component which has a carboxyl group and an amino group as end groups and whose double bonds are hydrogenated.
CONSTITUTION: A copolyamide resin is produced by copolymerizing by heating 5W99pts.wt. polyamide high-MW component having at least one of the repeating units represented by formulaI, wherein n is an integer of 5W12, and by formula II, wherein X is CmH2m (where m is an integer of 6W12), isophorone, phenylene or cycloalkylene and Y is ClH2l (where l is an integer of 4W10), phenylene or cyclohexylene, and 1W95pts.wt. polybutadiene component, average MW 500W 10,000, which has a carboxyl group and an amino group as end groups and whose double bonds are hydrogenated, to about 250°C for about 3hr under a stream of nitrogen. This copolyamide has low-water absorption and therefore, high-accuracy temperature control is possible when the copolyamide is used as a high-MW heat-sensitive substance.
