Melt free-radical grafting reactions between ethylene-propylene-dieneterpolymer (EPDM) and glycidyl methacrylate (GMA) were investigated in a batch mixer (170°C, 60rpm). Effect of dicumylperoxide (DCP) initiator and GMA functionalizing monomer concentrations was studied on the grafted EPDM characteristics. Titration results indicated an increase in the graft degree (GD) and gel content (GC) val...

The influence of quartz (silicon dioxide) content on main physical and mechanical properties composites based low density polyethylene is considered. It shown that the introduction a compatibilizer – copolymer high-density with maleic anhydride into composition improves compatibility mixed components. use synthesized wax as plasticizer made it possible to significantly improve deformability hig...

A conducting diblock copolymer of PS-b-P3HT was added to serve as a compatibilizer in a P3HT/PCBM blend, which improved the power-conversion efficiency from 3.3% to 4.1% due to the enhanced crystallinity, morphology, interface interaction, and depth profile of PCBM.

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...

The article is focused on analyzing the effect of functionalization and reactive processing on the morphological, thermal, rheological and mechanical properties of composites of isotactic polypropylene (PP), polystyrene (PS), poly(ethylene-vinyl acetate) (EVA), with cellulose fibers, hemp or oat as natural fillers. Both polymers and fibers were modified with bi-functional monomers (glycidyl met...

The effect of copolymers on the breakup and coalescence of polybutadiene ~PB! drops in polydimethylsiloxane ~PDMS! is studied using a four-roll mill flow cell. Copolymers are produced at the interface by a reaction between functionalized homopolymers. They reduce the interfacial tension and thus enhance breakup; they also inhibit coalescence of drops. Under the conditions of our experiments, th...

Starch- graft -poly(lactic acid) is put forward as an efficient compatibilizer of thermoplastic starch – PLA binary blend for a sustainable and high barrier film structures.

The blending of polymers leads to materials with the desired combined properties. These properties can further be improved by incorporation compatibilizer, organoclay, or both. In present manuscript, effects compatibilizer and as well their use on rheological, thermal, mechanical styrene copolymer blends, is examined. Styrene-containing copolymers blends were prepared melt-mixing in a twin scre...

The ability of commercial nanofillers Nanofil, Cloisite and by own way prepared MMT/ODA for PE and PP matrix was evaluated. Different types of mentioned type of nanofillers were added into polyethylene (PE) and polypropylene (PP) matrix in various concentrations. The amount of clays was calculated as 3 and 5 wt% to the weight of PE/PP. The PE/PP and nanofillers were mixed on a one screw KO Knea...
