The influence of polyethylene in the mechanical recycling of polyethylene terephtalate
TL;DR: In this paper, a series of proposed blends were injected in different molds and significant process parameters were evaluated to determine the final properties, and a morphological study using SEM and AFM was carried out, and the mechanical and thermal properties of the blends were analyzed to calculate the optimum proportion of PE content in PET waste, so that the recycling process can be performed in the easiest way possible without diminishing final properties.

Improvement of the mechanical behavior of bioplastic poly(lactic acid)/polyamide blends by reactive compatibilization
TL;DR: In this paper, a simple, continuous reactive extrusion processing method was examined for producing tougher bioplastic blends, where a p-Toluenesulfonic acid (TsOH) catalyst was added to two immiscible biobased polymers, poly(lactic acid) (PLA) and polyamide11 (PA11), to induce esteramide exchange reaction.

Phase structure and adhesion in polymer blends: a criterion for rubber toughening
TL;DR: In this paper, the effects of rubber particle size and rubber-matrix adhesion on notched impact toughness of nylon-rubber blends are analyzed. And the general condition for toughening is that the interparticle distance must be smaller than the critical value.

Influence of composition, crystallization conditions and melt phase structure on solid morphology, kinetics of crystallization and thermal behavior of binary polymer/polymer blends
TL;DR: In this paper, an investigation on the morphology, the crystallization and the thermal behavior of several binary crystallizable blends are reported, and it was found that the addition of a second non-crystallizable component causes drastic variations on some morphological and structural quantities of the semicrystalline matrix (isotactic polypropylene or nylon 6).

Morphology, crystallization and melting behaviour of films of isotactic polypropylene blended with ethylene-propylene copolymers and polyisobutylene
TL;DR: In this article, the crystallization, the morphology and the thermal behaviour of thin films of isotactic polypropylene (iPP) blended with elastomers such as random ethylene-propylene copolymers (EPM) with different ethylene content and polyisobutylene (PiB) were investigated by means of optical microscopy, differential scanning calorimetry and wide angle X-ray diffractometry.
