Attempts were made to modify polypropylene fibers by melt blending with polyethylene terephthalate in order to enhance the dyeability of the resultant fiber. Five blends of polypropylene/polyethylene terephthalate/compatibilizer were prepared and subsequently spun into fibers. Three disperse dyes were used to dye such modified fibers at boiling and 130 °C. The dyeing performance of the blend fi...

nanocomposite vulcunizates based on styrene-butadiene rubber (sbr), organoclay and a conventional sulfur curing system were prepared by melt blending process in an internal mixer. in order to study the effects of the type of interfacial compatibilizer on the properties of sbr and clay nanoparticles,three types of compatibilizers, maleic anhydride grafted ethylene-propylene diene rubber (epdm-g-...

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...

Polystyrene/polyolefin elastomer (PS/POE) (90/10 and 80/20 wt/wt) blends containing 1, 3, 5 phr halloysite nanotubes (HNTs) in the presence absence of a compatibilizer (polypropylene-graft-maleic anhydride) were prepared using melt-mixing technique. Scanning electron microscopic studies confirmed matrix-droplet morphology. Energy dispersive spectroscopy (EDS) mapping indicated that HNTs possess...

The overall goal of this study is to propose a new approach simplify the recycling process for producing high quality material from waste beverage bottles and other sources at lower cost by using mechanical chemical reactions inside injection molding machines in one-step process. water soft drink are made PET material, while caps mainly HDPE. blends HDPE incompatible. resulted has poor properti...

Currently, the ever-increasing post-consumer polypropylene (PP) plastics and agricultural forestry wastes that are relatively difficult to be degraded have led serious resource waste environmental pollution. To achieve rational utilization of resources meanwhile reduce potential influences on ecological environment, in this study, high-added-value biomass-derived composites were produced by che...

A significant portion of the global plastics market encompasses production polyolefin materials and especially polypropylene (PP) polyethylene (PE), as commodity polymers with a wide range applications. However, increase in generation unsustainable plastic waste requires close technological look-up to address this challenge adequately. In context, mechanical recycling is part strategies expecte...

mechanical properties of wood/plastic composites manufactured by polyethylene and polypropylene blends (pp/hdpe) were studied. the sebs (styrene-ethylene butylene-styrene) and epdm (ethylene-propylene diene monomer) were used as compatibilizers to improve the compatibility and miscibility of the interface between hdpe and pp phases. the sawdust and polymers were compounded using an internal mix...
