一种透明LLDPE薄膜树脂及其薄膜
摘要：
本发明公开了一种透明LLDPE薄膜树脂及其薄膜，该树脂是由乙烯和1-丁烯共聚生成，该树脂中化合物具有如下结构： 其中，20≤n1≤25，25≤n2≤250，1≤n3≤20，R1为-CH2CH3，R2为-(CH2)mCH3，且m≥100。本发明薄膜树脂具有宽分子量分布、含有独特短支链及少量长支链结构，这种结构能提高产品剪切敏感性，改善结晶形态，使得该树脂表现出更加优异的透明性和加工性，综合性能良好可用于有特殊需求的包装膜、缠绕膜等薄膜领域，是一种实用功能性薄膜树脂。
摘要（英）：

The invention discloses transparent LLDPE (linear low density polyethylene) thin-film resin and a thin film prepared from the same. The resin is prepared from ethylene and 1-butene through copolymerization, the structure of a resin compound is shown in the description, wherein n1 is larger than or equal to 20 and smaller than or equal to 25, n2 is larger than or equal to 25 and smaller than or equal to 250, n3 is larger than or equal to 1 and smaller than or equal to 20, R1 is -CH2CH3, R2 is -(CH2)mCH3, and m is larger than or equal to 100. The thin-film resin has a structure with broad molecular weight distribution, unique short branched chains and a few long branched chains, and by means of the structure, shear sensitivity of a product and crystallization morphology can be improved, so that the resin shows better transparency and machinability, has good overall performance, can be used in the thin-film fields of packaging films, wrapping films and the like with special requirements and is practical and functional thin-film resin.
