A binary blend of polycaprolactone and starch in 70:30 weight ratio (known under the tradename “Envar”) was blended in various weight ratios with organosolv lignin (L) and organosolv lignin butyrate (LB) by solvent casting and melt blending. The thermal transitions observed by DSC revealed behavior resembling that of native polycaprolactone (PCL). Depression in melting temperatures obtained by ...

It is well known that in blend modification, PC(Polycarbonate)/ABS(Acrylonitrile-Butadiene -Styrene) alloy polymers were used very common , but because of its high production cost and poor processing performance limited its application in marine materials. To improve the problem, We studied the behavior of ABS/PC alloy performance, and made a lot of exploration to increase the toughness, made i...

Melt copolymer chains are the main (most abundant) reaction product obtained when heating a blend of two (or more) condensation polymers (such as polyester + polycarbonate or polyester + polyamide or polyester + polyester) in which exchange reactions occur. In fact, during the melt-mixing reaction, an AB copolymer is formed and, as a consequence, the sample is a complex mixture made of three co...

The application of chaotic advection to polymer blends and composites originated in the corresponding author’s laboratory in 1991. Research has resulted in smart blending devices now being adopted by industry. In the accompanying talk, key concepts and recent results are described where polymer melt components are more controllably formed in situ into a wide variety of blend morphologies and wh...

Graphene nanoplatelet (xGnP) was investigated as a novel reinforcement filler in mechanical properties for poly(lactic acid) (PLA)/epoxidized palm oil (EPO) blend. PLA/EPO/xGnP green nanocomposites were successfully prepared by melt blending method. PLA/EPO reinforced with xGnP resulted in an increase of up to 26.5% and 60.6% in the tensile strength and elongation at break of the nanocomposites...

A new strategy for synthesizing well-defined, chain-end-functionalized polymers containing multiple hydrogen-bonding (MHB) groups capable of heterodimerization in both solution and the melt has been developed. Two complementary MHB systems were chosen for initial studies: 2-ureido-4[1H]-pyrimidinone (UPy) and 2,7diamido-1,8-naphthyridine (Napy) and ATRP initiators containing either UPy or Napy ...

Carbon nanomaterial particles were selectively distributed in an incompatible and high-melting-temperature polymer blend interface, or in a particular phase, to obtain conductive composites. The composite products revealed poor morphology stability and mechanical performance due to processing several times. Poly(phenylene sulfide) (PPS) and poly(ether ether ketone) (PEEK) polymers with large di...

In this paper, intercalation of nanoclay in the miscible polymer blend of poly(vinylidene fluoride) (PVDF) and acrylic rubber(ACM) was studied. X-ray diffraction was used to investigate the formation of nanoscale polymer blend/clay hybrid. Infrared spectroscopy and X-ray analysis revealed the coexistence of β and γ crystalline forms in PVDF/Clay nanocomposite while α crystalline form was found ...

Abstract In Polyethylene terephthalate (PET) processing the raw materials are purified terephthalic acid (PTA), moderately (MTA), monoehalene glycol (MEG). The of PTA is very difficult and costly. For reducing percent we using different percentages MTA blend in PET processing. affected properties polyester melt spinning process. such as elongation, tenacity, molecular chain length, b-color IV, ...
