Summary:

PC/ABS blends are being used in applications for automotive parts because of their good balance in heat resistance, impact strength, and dimensional stability.The weld line strength of the blends is, however, much inferior to that of each base polymer, and this poor strength sometimes causes trouble in the performace of the final product.A study was made on the composition of PC/ABS blends for improving this poor weld line strength.As the result of this study, it was found that a specific composition of ABS (high molecular weight SAN, higher rubber content, and high molecular weight PC) and an additive (modified polyolefine) could remarkably improve the weld line strength.Electron microscopic photographs and physical properties showed that the specific additive could improve the compatibility of PC and ABS resins.This paper focuses on the conclusion of the development effort of the improved PC/ABS blend
