Abstract
Abstract In-situ fibrillation and intercalation structure are favoring to improve the properties of polymer blends. In this work poly(butylene succinate)/poly(lactic acid) blends containing such structures have been achieved via volume pulsating elongation flow instead of strong shear. The mechanical properties, crystallization properties and micromorphology of the extruders were well investigated. The results showed that PBS and PLA were partially miscible and the compatibility improved mandatorily by the elongation flow. Evenly distributed and oriented in-situ sub-micron fibers (PLA content
