PURPOSE:To obtain a resin composition having high rigidity, excellent heat- resistance, low friction coefficient and high abrasion resistance, by compounding nylon 4,6 with specific amounts of potassium titanate whisker and/or silicon carbide whisker and optionally a lubricant. CONSTITUTION:The objective composition can be produced by melting and mixing (A) 100pts.wt. of polytetramethylene adipamide (nylon 4,6) with (B) 5-100pts.wt., preferably 10-80pts.wt. of (B1) potassium titanate whisker (e.g. potassium 4-titanate fiber) preferably having an average fiber diameter of <=2mum, an average fiber length of 5-100mum and an aspect ratio of >=10 and/or (B2) silicon carbide whisker preferably having an average fiber diameter of <=2mum, an average fiber length of 20-500mum and an aspect ratio of >=10 and, if necessary, (C) <=40pts.wt., preferably 1-20pts.wt. of a lubricant (preferably molybdenum disulfide).
