Title:
POLYPHENYLENE ETHER RESIN COMPOSITION
Document Type and Number:
Japanese Patent JPH03285949
Kind Code:
A
Abstract:
PURPOSE:To obtain a composition suitable for engineering plastic, having excellent heat resistance, rigidity, dimensional stability, appearance, etc., by blending a polyphenylene ether containing a specific amount of a cyclic end group such as 6 coumarone skeleton with a specific amount of inorganic filler. CONSTITUTION:100 pts.wt. polyphenylene ether resin containing >=0.01, preferably >=0.2 based on 100 phenylene ether units of a cyclic end group shown by the formula (R1 to R5 are H, alkyl, halogen, etc.; R6 to R9 are H, alkyl, alkyl, alkenyl, etc., and R6 may be bonded to R7 and R8 to R9 independently, respectively, to form ring of spiro cyclic structure) and having 1,000-100,000, preferably 10,000-30,000 number-average molecular weight is blended with 1-150 pts.wt., preferably 5-50 pts.wt. inorganic filler (e.g. iron oxide or zinc oxide).
