The effect of main technological factors on moldability of crystallizable (LDPE, HDPE, P~ and amorphous (ABS, PC) thermoplastics has been studied during their melt processing under t conditions which simulate the extrusion-molding technology. The results obtained show that ( flowability of the polymer in a mold depends on a series of technological parameters, rheol relaxation and thermal properties of the polymer. It has been found that the flowability is the nr factor that determines the PM moldability characterized by the melt flow distance in the mo cavity.
