Mesophase pitch-based carbon fibres have excellent resistance to plastic deformation (up 840 GPa); however, they very low strain failure (0.3) and are considered brittle. Hence, the development of pitch fibre precursors able be plastically deformed without fracture is important. We previously, successfully developed precursor with high ductility (low brittleness) by blending linear low-density ...

Abstract Rotomolded uncompatibilized composites of LLDPE with softwood and hardwood flour dispersed phases are compared contrasted respect to their static (tensile, flexural impact) dynamic (creep modelling, storage loss moduli) mechanical properties transport (oxygen permeability). The analysed as a function phase weight fraction pre post ethanol sorption. Vital structural such the equilibrium...

Polyethylenes (PE) are the most commonly occurring ingredients for post-consumer recyclates (PCR). The structure–property relationships of different types model PE-based blends established using multiple thermo-rheological analyses. Although considered “simple”, complex behavior is experimentally demonstrated first time metallocene-catalyzed, linear, low-density polyethylenes (mLLDPE) with micr...

This article introduces a new mixed integer linear programming model of the optimal scheduling of multistage polymer plants. Most commodity polymer plants for products such as HDPE, PP, LDPE, LLDPE, PVC, PS, K-RESIN and CB are composed of reaction, extrusion and packaging stages. The operation of the reaction stage has the characteristics of both a batch process in that one process produces mul...
