    Abstract: PURPOSE:An antistatic improver consisting of a melted hindered phenol and a sulfonate salt is added to the block polyether-polyamide on spinning to give a high antistatic polymer for clothes with reduced discoloration by use of simple devices. CONSTITUTION:A mixture of antistatic agents, which is made by adding an alkali metal salt of a sulfonate such as sodium dodecylbenzenesulfonate to a hindered phenol such as 1,3,5-trimethy1-2,4,6-tri(3,5-di-tert-butyl-4-hydroxybenzyl) benzene melted by heating up to 260 deg.C, is added to a block polyetherpolyamide such as a polycondensate between polyethylene glycol diamine and adipic acid after polymerization or on spinning to give the objective high antistatic polymer or its fibrous material.

    Abstract: PURPOSE:To obtain nylon 66 polymer which can be spun at a high speed in excellent operability and is prevented from undergoing end breakage, by polycondensing polyhexamethylene adipate by adding epsilon-caprolactam and a metal phenylphosphonate before completion of the polycondensation. CONSTITUTION:Polyhexamethylene adipate is polycondensed. Before completion of the polycondensation, 0.1-5wt%, based on the formed polymer, epsilon-caprolactam and/or epsilon-aminocaproic acid are added and 1-100ppm (in terms of P based on the formed polymer) of a metal phenylphosphonate selected from among an alkali (alkaline earth) metal phenylphosphonate and a reaction product between phenylphosphonic acid and an alkali (alkaline earth) metal hydroxide is further added to the reaction system. The polycondensation is brought to completion to obtain the titled polymer which can be spun with controlled end breakage even when it is spun at a speed as high as 3,000m/min or higher and can give a woven fabric of excellent feeling.
