 Full text | Abstract: The interdependence between the crystallinity of poly(butylene succinate-co-adipate) (PBSA) and its biodegradation capacity in blends with low-density polyethylene LDPE has been studied. The LDPE/PBSA blends were prepared by extrusion. As a compatibilizing agent, block copolymer polystyrene-block-poly-(ethylene-co-butylene)-block-polystyrene (FG) modified by maleic anhydride was used. The biodegradation test was performed in a soil and the crystallinity was analysed by the WAXS method. It was found that, six months after the test in question, the degradation of the crystalline part of PBSA took place. In the presence of FG, the PBSA degraded more rapidly due to the lower degree of crystallinity of the polyester. |
