Cotton-Jute Blending-Changes in Blend Composition During Processing

Textile Research Journal, 1981
The composition of cotton-jute blends, at various stages of processing from blowroom to ring frame, has been analyzed using an x-ray diffraction method. The study revealed that the reduction in the nominal jute content observed in the ring yarn is due to preferential losses of this fiber under the licker-in region.

Predicting Morphologies of Solution Processed Polymer:Fullerene Blends

Journal of the American Chemical Society, 2013
The performance of solution processed polymer:fullerene thin film photovoltaic cells is largely determined by the nanoscopic and mesoscopic morphology of these blends that is formed during the drying of the layer. Although blend morphologies have been studied in detail using a variety of microscopic, spectroscopic, and scattering techniques and a large

Polymer blends. III. Processing optimization

Acta Polymerica, 1984
AbstractThe paper presents a part of the data obtained in a study on the possibilities of processing optimization of some polymer blends containing polyethylene, polystyrene, poly(vinyl chloride) and ethylene vinylacetate copolymer as compatibility agent.

Processable intrinsically conductive polymer blends

Journal of Vinyl Technology, 1992
Abstract Blends of intrinsically conductive polymers (ICPs) with conventional thermo‐plastics exhibit conductivities approaching those of neat ICPs and can be processed using conventional thermoplastic processing equipment. They display good environmental stability and mechanical properties suitable for commercial applications.

Interface-Induced Coarsening Process in Polymer Blends

Journal of Colloid and Interface Science, 2001
The coarsening process of the droplets in a two-phase polymer blend (PP/EVAc) was studied under two-dimensional and three-dimensional conditions using a phase contrast microscope and computer image analyzer. The results showed that under three-dimensional conditions the growth of the droplet's radius with time follows r(3) approximately t(1.01 ...

Processing and Properties of Biopolymer/Polyhydroxyalkanoates Blends

Journal of Polymers and the Environment, 2011
In this paper, the processability and the performance of a biodegradable polymer, Mater-Bi, and of its blends with either a sample of poly (hydroxy alkanoates) (PHA) or with bacterial biomass containing PHAs were compared. Adding PHA or directly the biomass containing it allows improving the processability of the matrix.

Poly (lactic acid) blends: Processing, properties and applications

International Journal of Biological Macromolecules, 2019
Poly (lactic acid) or polylactide (PLA) is a commercial biobased, biodegradable, biocompatible, compostable and non-toxic polymer that has competitive material and processing costs and desirable mechanical properties. Thereby, it can be considered favorably for biomedical applications and as the most promising substitute for petroleum-based polymers in

Processing of polypropylene blends

1999
Only two classes of polypropylene (PP) blends have achieved commercial success: blends with polyolefins and with polyamides (PA). With PP/polyolefin blends, the goal is either to improve the impact resistance of the base resin (impact-modified PPs) or to produce thermoplastic elastomers (dynamically vulcanized blends).

Processable conductive blends of polyaniline/polyimide

Journal of Applied Polymer Science, 1998
By using camphorsulfonic acid (CSA) to protonate polyaniline (PANI), the counterion enabled the PANI–CSA complex processable as a solution phase. So camphorsulfonic acid (CSA)-doped polyaniline/polyimide (PANI/PI) blend films were prepared by the solvent casting method using N-methylpyrrolidinone (NMP) as a cosolvent followed by thermal imidization ...

Gravimetric blending meets processing needs

Plastics, Additives and Compounding, 2000
Abstract Custom moulders can realize significant cost savings and improve plant efficiencies through precise blending of colour concentrate and other additives. With rising costs of these materials, it becomes very important that these ingredients are dispensed highly accurately and that no waste occurs during colour change.
