POLY M-PHENYLENE TEREPHTHALAMIDE FILM WHICH HAS AN EXCELLENT HEAT RESISTANCE AND AN EXCELLENT INTENSITY BY A STRONG INTERACTION BETWEEN POLYMER CHAINS WHICH ARE CAUSED BY A HYDROGEN BOND AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A poly m-phenylene terephthal amide film has a high crystalline property, a high orientation property, an excellent intensity, and an excellent heat resistance.;CONSTITUTION: A poly m-phenylene terephthal amide film is manufactured as 'a poly m-phenylene terephthal amide composition which is manufactured in m-phenylene diamine and terephthaloyl chloride and is formed by using N-methylpyrrolidone which includes CaCl2 as a solvent'. The CaCl2 is mixed with 'N-methylpyrrolidone which includes the CaCl2' in the amount of 1-5 weight%. 'N-methylpyrrolidone which includes the CaCl2' is manufactured at 70-90 °C for 80-140 minutes in a nitrogen atmosphere by stirring a mixture after mixing CaCl2 with N-methylpyrolidone.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Dissolving step; (BB) Polymerizing step; (CC) Neutralizing step
