基于丙烯的三元共聚物
摘要：
一种丙烯、乙烯、1-丁烯三元共聚物，其含有：a)1.8wt％至5.9wt％的乙烯衍生单元；b)2.0wt％至4.5wt％的1-丁烯衍生单元；其中：i)C2wt％/C4wt％的比例范围为0.9至1.3；其中C2wt％是乙烯衍生单元的重量百分数，C4wt％是1-丁烯衍生单元的重量百分数；ii)熔体流动速率范围为1.0g/10min至30.0g/10min，iii)25℃下，二甲苯可溶级分为10wt％至30wt％。
摘要（英）：

A propylene, ethylene, 1-butene terpolymer containing: a) from 1.8 wt% to 5.9 wt% of ethylene derived units; b) from 2.0 wt% to 4.5 wt% of 1 butene derived units; wherein: i) the ratio C2wt%/C4wt% ranges from 0.9 to 1.3; wherein C2wt% is the weight per cent of ethylene derived units and C4wt% is the weight per cent of 1-butene derived units; ii) the Melt flow rate ranges from 1.0 to 30.0 g/10 min, iii) the xylene soluble fraction at 25 DEG C is comprised between 10 wt% and 30 wt%.
