一种胺端基型超支化聚合物对PHBV的增韧改性研究
Toughening Modification of Poly (hydroxybutyrate-co-hydroxyvalerate) by an Amino-terminated Hyperbranched Polymer
摘要
Abstract
Blends of poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) with an amino-terminated hyperbranched polymer (HBP) were prepared by a melt-blending method and then characterized by differential scanning calorimetry,rotational rheometer,polarized light microscopy,scanning electron microscope,and tensile and impact tests.The results indicated that the blend containing 1.0 wt ％ HBP achieved an increase in impact strength by 31.3 ％ and in elongation at break by 45.5 ％.Compared with pure PHBV,the crystallinity of the blend was also reduced from 71.7 ％ to 59.1％,whereas the tensile strength almost did not change.关键词
