Poly(lactic acid) (PLA) and starch copolymers are obtained by reactive blending varying the starch compositions from 0 to 60%. PLA is functionalized with maleic anhydride (MA), obtaining PLA-g-MA copolymers using dicumyl peroxide as an initiator of grafting in order to improve the compatibility and interfacial adhesion between the constituents. PLAþ starch blends without a compatibilizer do not...

In the present investigation, a compatibilized blend of thermoplastic polyurethane (TPU) and polydimethylsiloxane (PDMS) is prepared by using copolymer of ethylene and methyl acrylate (EMA) as a reactive compatibilizer. Detailed in vitro biocompatibility studies were carried out for this compatibilized blend and the material was found noncytotoxic towards L929 mouse fibroblast subcutaneous conn...

The blending of aliphatic polyolefins and aromatic poly(ethylene terephthalate) (PET) based on different intrinsic viscosities (IV) was conducted in a torque rheometer. The comparison of blend components in terms of low density polythene (LDPE) and polypropylene (PP) in blending with PET was investigated, and the effects of the IV and proportion of PET on polymer blends are discussed in detail....

Immiscible homopolymers are often blended mechanically to obtain blends with properties significantly superior to those of the component polymers. The creep recovery of such blends was studied in the previous paper, henceforth referred to as I. Surface-active compatibilizers are commonly added to such blends to improve blending of the immiscible phases and to improve the mechanical properties o...

The rheological properties of blends of immiscible homopolymers have received much attention in recent years (Tucker and Moldenaers 2002). Several publications have been devoted to examining the relationship between the rheology and morphology of two-phase blends. A key strategy employed by many researchers was to conduct experiments on ‘‘model’’ blends that were comprised of rheologically-simp...

Adding acid-modified resin compatibilizers is essential for plastic composites reinforced with carbon-neutral cellulosic filler. Researchers have measured the efficacy of adding a compatibilizer in context mechanics. However, it necessary to microscopically clarify how actually works quality control and further expansion applications. In this review, author first describes situation presents is...

the purpose of this study was to evaluate effects of nano-clay particles and oxidized polypropylene as compatibilizer on the decay resistance of wood plastic composite against coriolus versicolor fungi. in order to provide oxidized polypropylene as compatibilizer, polypropylene was oxidized in the presence of air oxygen in 2 hours by internal mixer. afterwards, wood fibers, polypropylene, nano-...

The copolymer VAMA was synthesized from vinyl acetic and maleic anhydride. A new all-polymeric blend with a high dielectric constant (ε) has been developed by blending polyvinylidene fluoride (PVDF) with vinyl acetic-maleic anhydride modified polyamide (PA66-g-VM). The blend shows high dielectric constants (εblend = 20) and excellent mechanical properties. The SEM investigations suggest that th...

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...
