PURPOSE: A flexibilized resin composition, obtained by incorporating a polyether ester amide with polyvinyl cloride, and having improved flame retardancy, low and high temperature characteristics and mechanical strength.
CONSTITUTION: A resin composition obtained by incorporating 5W95wt% polyether ester amide, constituted of a ≥6C aminocarboxylic acid or lactam, preferably 11-aminoundecanoic acid or 12-aminododecanoic acid, a poly(alkylene oxide)glycol having a number-average molecular weight of 300W6,000, preferably poly(tetramethylene oxide)glycol, 4W20C dicarboxylic acid preferably terephthalic acid or sebacic acid, etc., and having a melting point of 70W200°C with 95W 5wt% polyvinyl chloride. The polyether ester amide is preferably prepared by charging the three components simultaneously into a reactor, melt mixing the components, and polymerizing the components in one step in a high vacuum.
