Abstract
Disclosed herein are pultruded articles prepared from a reinforcing material and a polyamide matrix made by the process of impregnating a reinforcing material with a polyamide forming reaction mixture and then pultruding the impregnated reinforcing material through a die while polymerizing the polyamide forming reaction mixture to form a polyamide matrix, wherein the temperature of the material being pultruded is at least about at the lower end of the melting range of the polyamide.
Claims7
A pultruded article comprising a reinforcing material and a polyamide matrix which is made by a process comprising the steps of:
- (a) impregnating a reinforcing material with a polyamide forming reaction mixture comprising at least one monomer, an initiator and a catalyst;
- (b) pultruding the reinforcing material impregnated with the polyamide reaction mixture through a die;
- (c) polymerizing the polyamide forming reaction mixture in the die to form a polyamide matrix while pultruding the impregnated reinforcing material;
- (d) maintaining the temperature of the impregnated reinforcing material being pultruded at a temperature which is at least about at the lower end of the melting range of the polyamide matrix;
- (e) conveying the impregnated reinforcing material to a cooling zone;
- and
- (f) recovering the pultruded article.
