Abstract
PURPOSE: To prepare the title copolyamide having a specific repeated unit which provides a fiber with excellent mechanical property and dimentional stability in wetted state.
CONSTITUTION: To an equimolar mixture (salt) of a compound designated as a formula HOOC-AL2-COOH and a formula H2N-AL3-NH2 or to a compound designated as a formula I, an equimollar mixture of a compound designated as a formula HOOC-Ar-COOH and a formula H2N-AL1-NH2 is added and heated and pressurized to 240W320°C, 0W30atm. within an aqueous medium, moreover melted and polymerized at below 320°C to obtain a copolyamide containing an aromatic oligoamide with a logarithmic viscosity index (q inh) of above 0.4 comprising repeated units of a formula II and III or IV (Ar is a formula V, VI; m is 0W2; n is 1W 3; AL1WAL4 are divalent aliphatic group).
