POLYBUTENE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a polybutene resin composition that has excellent pipe high-speed moldability without damage of compressive strength under a high temperature condition occurring when carboxylic amide compound is used. SOLUTION: This invention provides a polybutene resin composition by adding 0.001 to 5 pts.wt. of carboxylic amide and 0.1 to 5 pts.wt. of talc to 100 pts.wt. of polybutene. Further, a polybutene resin additionally including 0.01 to 5 pts.wt. of titanium oxide is provided. The carboxylic amide and the talc commonly function as crystalline nuclei. These polybutene resin compositions preferably has a semi-crystallization time (T1/2) (90°C) of 96 to 200 seconds at 90°C. This invention also provides the molded products from the resin composition.
