Vitrimers are a new class of materials that consist chemically cross-linked networks engage in thermoactivated associative exchange reactions. These reactions can impart malleability, healing, and recyclability properties to thermosets. In this study, one-step protocol prepare linear low-density polyethylene (LLDPE) vitrimer-like with disulfide bonds via reactive blending is presented. The cros...

In this study, rice-straw (RS) filled high density polyethylene (HDPE) composites were manufactured by extrusion and injection molding. Three compatibilizers, which are unfunctionalized ethylene/propylene copolymer (uEPR), maleic anhydride grafted EPR (EPR-g-MA) and PE-g-MA, and their combinations were introduced to strengthen fibermatrix interphase. The mechanical and morphological properties ...

Fabrication of biodegraded composite from polypropylene, polypropylene grafted maleic anhydride, and chempedak seed (Artocarpus integer) starch has been conducted. The stages were prepared Cempedak seed, grafting process anhydride on fabrication with a composition ratio PP: PP-g-MA: (9.5:0.5:0.1)g, (9.5:0.5:0.2)g, (9.5:0.5:0.3)g, (9.5:0.5:0.4)g, (9.5:0.5:0.5) g, (10:2)g. composites obtained cha...

Cross-linked polyethylene (XLPE) is primarily used as a coating and insulator for electrical wires cables. The cross-links render recycling through remelting unfeasible, XLPE waste usually incinerated or sent to landfills. Previous investigations showed that increased the impact strength of commodity thermoplastics. Hence, incorporating in polyamide 12, an engineering thermoplastic, was studied...

In this work, ternary polymer blends based on polypropylene (PP)/ polyethylene terephthalate (PET) /poly(styrene-b (ethylene-co-butylene)-b-styrene) (SEBS) triblock copolymer and a reactive maleic anhydride grafted SEBS (SEBS-g-MAH) at various compositions were prepared by co-rotating twin screw extruder. The effects of PET, SEBS and SEBS-g-MAH compatibilizer on morphology of the blends were ex...

<p class="JARTEAbstract">In this study was analyzed the effect of three different compatibilizers polyethylene-graft-maleic anhydride (PE-g-MA), unmodified halloysite nanotubes (HNTs), and HNTs treated by silanization with (3-glycidyloxypropyl) trimethoxysilane (GLYMO) (silanized HNTs) in blends bio-based high-density polyethylene (bioPE) poly(butylene succinate) (PBS) a weight ratio (70/...

Linear polypropylene (PP)—composed of long polymer chains devoid of branches or crosslinked structure—and blends of PP with olefinic elastomers are widely used in the automotive and packaging industries. What makes foams produced with these materials of growing interest is their potential to replace the prevalent thermoset polyurethane foams which are not recyclable. However, the production of ...

The polycondensation of tetrahydrofuran with maleic anhydride catalyzed by Maghnite-H+ (Mag-H) was investigated. Maghnite is a montmorillonite sheet silicate clay that is exchanged with protons to produce Maghnite-H [1]. It was found that the polymerization in bulk is initiated by Mag-H in the presence of acetic anhydride at 40 degrees C. The effects of the amounts of Mag-H and acetic anhydride...
