Abstract
There is disclosed a styrenic resin pellet having a length in the range of 2 to 100 mm which comprises a (A) styrenic polymer having syndiotactic configuration and containing a polar group and at least 10% by weight of a (B) glass fiber which is surface-treated with a coupling agent, is impregnated with the styrenic polymer, and has a length equal to the length of the pellet. The styrenic resin pellet is imparted with excellent moldability and improved in general physical properties such as impact resistance and heat resistance, thereby making itself well suited to the raw material for producing molded articles excellent in practical characteristics such as tensile creep at elevated temperatures higher than the glass transition temperature and vibrational fatigue characteristics at elevated temperatures.
