Abstract: A copolyamide comprised of undecamethylenehexahydroterephthalamide units and hexamethylenehexahydroterephthalamide units having a trans isomer ratio of hexahydroterephthalic acid residues of 57 to 83 percent is provided. The copolyamide is suitable for injection and extrusion molding. The copolyamide is prepared by a process comprising heating an equimolar salt of undecamethylenediamine and hexahydroterephthalic acid and an equimolar salt of hexamethylenediamine and hexahydroterephthalic acid at a maximum temperature of about 280 to 360 DEG C. to stably melt-polymerize the copolyamide. A copolyamide molding composition comprised of the copolyamide and an inorganic reinforcing agent can be formed into various molded articles having excellent properties.

Abstract: PROBLEM TO BE SOLVED: To obtain excellent heat resistance by reacting a copolymer of a (meth)acrylic ester monomer and an addition-polymerizable monomer with NH3 or a primary amine in the presence of a nitrogenous heterocyclic compound. SOLUTION: A mixture of a (meth)acrylic ester monomer (a) such as methylmethacrylate and other addition-polymerizable monomer(s) such as styrene in a given proportion is heated together with a polymerization initiator and a chain transfer agent to react the monomers. The resultant copolymer is mixed with 0.1-10 pts.wt. nitrogenous heterocyclic compound such as 2-pyridone per 100 pts.wt. the copolymer and with about 0.1-10mol of an imidating agent comprising NH3 or a primary amine such as p-toluidine per mol of the two kinds of acrylic ester structural units. The mixture is reacted at 100-350 deg.C to obtain an imidated copolymer made up of 1-98% addition-polymerized structural units (b) derived from the monomer (a), 1-98wt.% imidated structural units derived from the units (b), and 0-98% other addition-polymerized structural units.
