Effect of a compatibilizer on the morphology and properties of polypropylene/polyethylentherephthalate spun fibers [PDF]

, 2017
Fibers spun by melt spinning of binary and ternary polypropylene/ polyethylenetherephthalate blends have been produced and characterized in order to investigate the effect of a compatibilizer on their morphology and mechanical properties.

Record‐High Latent Heat, Ultra‐Fast Relaxation and Closed‐Loop Recycling Double‐Brush Polymer Networks for Self‐Adaptive Thermal Interface Management

Advanced Science, EarlyView.
By grafting dense long double‐brush chains, we synthesized bottlebrush networks with high theoretical enthalpy. Their low entanglement, combined with dynamic bonds, promotes crystalline domain reorganization and minimizes enthalpy loss, achieving a record enthalpy of 240.7 J·g−1.

Improvements in the Rheological Properties, Impact Strength, and the Biodegradability of PLA/PCL Blend Compatibilized by Electron-Beam Irradiation in the Presence of a Reactive Agent

Advances in Materials Science and Engineering, 2018
In this study, we blended poly(ε-caprolactone) (PCL) into poly(lactic acid) (PLA) and compatibilized these PLA/PCL blends by electron-beam irradiation in the presence of a reactive agent to overcome drawbacks of PLA.

A Novel Reactive Processing Technique: Using Telechelic Polymers To Reactively Compatibilize Polymer Blends

ACS Applied Materials & Interfaces, 2009
Difunctional reactive polymers, telechelics, were used to reactively form multiblock copolymers in situ when melt-blended with a blend of polystyrene and polyisoprene. To quantify the ability of the copolymer to compatibilize the blends, the time evolution of the domain size upon annealing was analyzed by SEM.
