BLENDS OF STYRENE BUTADIENE COPOLYMERS WITH POLY(LACTIC ACID)
Abstract:
The present invention relates to a polymer blend comprising 75-99.5% (w/w) of at least one polylactic acid) (PLA) and 0.5-25% (w/w) of at least one styrene butadiene copolymer containing at least 50% (w/w) styrene. The present invention further relates to the use of such polymer blend for producing products and to the resulting products. Moreover, an object of the present invention is the use of a styrene butadiene block copolymer having a dendrimer structure comprising 50-85% (w/w) styrene as an additive of polymer blends comprising at least 50% (w/w) of PLA and a method of producing the polymer blend according to the invention.
Abstract(Chinese):

本发明涉及包含75-99.5％（w / w）的至少一种聚乳酸（PLA）和0.5-25％（w / w）的至少一种含至少50％ （w / w）苯乙烯。 本发明还涉及这种聚合物共混物用于生产产品和所得产品的用途。 此外，本发明的目的是使用具有包含50-85％（w / w）苯乙烯的树枝状聚合物结构的苯乙烯丁二烯嵌段共聚物作为聚合物共混物的添加剂，其包含至少50％（w / w）的PLA 以及制备本发明的聚合物共混物的方法。
