摘要
应用差示扫描量热法,考察了几种不同牌号的LDPE与HDPE配伍的熔融共混物的热行为.发现熔融共混物的热行为特征与溶液共混共沉物的不同,表明不同品种PE共混物的晶相能否形成共晶与其共混方法有关。
The thermal behavior of LDPE/HDPE blends prepared by melt mixing is investigated by DSC.It has been found that the characteristics of the thermal behavior of those LDPE/HDPE blends is different from that prepared by co-dissolvingprecipitating procedure,and in the LDPE/HDPE blends,whether cocrystal of LDPE and HDPE is able to form is related to the mixing method.It has been further proved that formation of co-crystal is related to chemical structure of these PEs(branching degree and kind of branched chain etc.)
