Abstract
A fiber-reinforced chlorinated polyethylene composition comprises 100 parts by weight of a continuous phase of a chlorinated polyethylene and 2-100 parts by weight of a polyamide dispersed in the continuous phase in a fine short fiber form. Further a process comprises kneading a chlorinated polyethylene and a fiber-formable polyamide at a temperature not lower than the melting point of the polyamide and then stretching the kneaded product to obtain the above fiber-reinforced chlorinated polyethylene composition. When in the above process, the kneading is effected by further adding a reactive binder, there can be obtained a fiber-reinforced chlorinated polyethylene composition wherein the compatibility and dispersion of the fiber-formable polyamide with and in the chlorinated polyethylene are improved. The fiber-reinforced chlorinated polyethylene composition is superior in mechanical properties, fatigue resistance and heat resistance and further has good processability, and can be suitably used in the wide field of chlorinated polyethylene applications.
