聚烯烃粘合剂组合物
摘要：
本发明公开一种粘合剂组合物。粘合剂组合物包含马来化聚烯烃和LLDPE。LLDPE通过齐格勒-纳塔催化剂制备，所述催化剂包含MgCl2载体、Ti(IV)络合物和电子给体。催化剂具有大于或等于7的Mg/Ti摩尔比。优选Ti(IV)络合物为TiCl4，电子给体为四氢呋喃。优选粘合剂包含35至95%重量LLDPE和5至65%重量马来化聚烯烃。
摘要（英）：

Disclosed is an adhesive composition. The adhesive composition comprises a maleated polyolefin and an LLDPE. The LLDPE is made by a Ziegler-Natta catalyst which comprises a MgCl2 support, a Ti(IV) complex, and an electron donor. The catalyst has an Mg/Ti molar ratio greater than or equal to 7. Preferably, the Ti(IV) complex is TiCl4, and the electron donor is tetrahydrofuran. Preferably, the adhesive comprises from 35 to 95 wt % of the LLDPE and 5 to 65 wt % of maleated polyolefin.
