2017年2月24日 · Polyethylene (PE) and isotactic polypropylene (i PP) are the two most widely used commodity plastics and thus make up a large fraction of the waste stream. However, the two plastics will not mix together, which limits options for dealing with mixed waste and decreases the value of recycled products.

2025年2月14日 · To support the formation of trapped entanglements and co-crystals at the interface of iPP/PE blends with BC1 as a compatibilizer, we performed peel tests on iPP/BC1/PE three-layer laminates, providing a more direct measurement of the …

2001年6月1日 · In this paper, the chain structure and structural distribution of an iPP/EPR in-situ blend based on a spherical TiCl 4 /MgCl 2 catalyst is studied by temperature gradient extraction fractionation combined with 13 C NMR, FT-IR, DSC and WAXD.

Interfacial compatibilization of phase-separated PE and iPP with tetrablock copolymers enables morphological control, transforming brittle materials into mechanically tough blends.

2017年2月23日 · 相分离的 PE 和 iPP 与四嵌段共聚物的界面相容化可实现形态控制，将脆性材料转化为机械韧性的混合物。 普通等级的 PE 和 iPP 不会粘附或混合，这给回收这些材料带来了挑战。 我们使用等选择性烯烃聚合引发剂合成了 PE/iPP 多嵌段共聚物。

研究了缠结和共结晶在 iPP/PE 共混物与 PP 基二嵌段共聚物 （BCs） 相容中的作用。 根据两种不同的 BCs，iPP/HDPE 和 iPP/LDPE 共混物 （30/70 wt%/wt%） 和不同的加工条件的选择，建立了一个智能的实验设计。

2021年8月21日 · In this work, based on the free radical branching reaction, a co-branching reaction of isotactic polypropylene (iPP) and high-density polyethylene (HDPE) blends was carried out in the presence of the peroxide, free radical regulator and multifunctional acrylate monomer, and a star-like long-chain branching (LCB) copolymer was obtained.

2017年2月24日 · Interfacial compatibilization of phase-separated PE and i PP with tetrablock copolymers enables morphological control, transforming brittle materials into mechanically tough blends.

We synthesized PE/iPP multiblock copolymers using an isoselective alkene polymerization initiator. These polymers can weld common grades of commercial PE and iPP together, depending on the molecular weights and architecture of the block copolymers.

2006年1月1日 · The branched-PE/i-PP reactor blends that contain more than 20 wt% of the branched PE were prepared through an in-situ gas-phase polymerization of ethylene in iPP particles catalyzed by impregnated α-diimine nickel.
