PURPOSE:To obtain the titled composition suitable as small plates for automobiles and snow mobiles, having low water vapor absorption, excellent dimensional stability, mechanical properties and surface appearance, by blending an omega-lactam melt with a specific amount of hydrocarbon wax. CONSTITUTION:100pts.wt. omega-lactam (e.g. gamma-butyrolactam, etc.) melt containing a polymerization catalyst (e.g. alkali metal, etc.) and/or omega-lactam melt containing a polymerization initiator (e.g. toluene diisocyanate, etc.) is blended with 1-10pts.wt. hydrocarbon wax. |
