The evaluating methods and progress in the research of the compatibility evaluation of amorphous/amorphous polymer blend,crystalline/amorphous polymer blend and crystalline/crystalline polymer blend are reviewed,and the evaluation methods for compatibility of polymer blend are also discussed briefly.
The relationship between polymer blend's composition and its properties has so far only been described qualitatively or semi-quantitatively because the complexity of structure and characteristics of the polymer blends.
The relationship between sol fraction and radiation dose of differentweight ratio polymer blends has been studied. The experiment results show that therelationship, R(S+S~(1/2))=1/q_0u_1+(p′_0/q_0)R~β,is also suitable to this polymer blend system. The method to calculate the β value ofpolymer blend system (EVA/LDPE) has been established.
The morphology of a multilamellar polymer blend is a major structure factor which determines its properties. For the difficulty and the importance both in theory and in application, it was highlight in multiphase polymer blend research to study the factors, especially the shape, size and distribution of its dispersed phase, which influences the morphology of a multiphase polymer.
The LLDPE/PS alloys were prepared through polymer blend and the effects of different proportion of blend and blend temperature on the properties of the alloys were investigated.
In this paper a method of particle size measurement introduced into the size and shape measurement of dispersed phase in polymer blend is found feasible.
The particle size distribution was obtained through computer's processing the SEM photographs of polymer blend(PP/PA1010)broken surface after brittle failure and counting particle numbers.
Studies on Equilibrium State of Phase Separation and Nonequilibrium State of Rheological Property of Polymer Blend by Nonlinear Sub-cluster Statistical Theory
The scanning transmission electron microscopy (STEM) of analytical electron microscope was applied to study of two types of polymers,and,with ABS/PVO polymer blend and keratin fiber as materials,the process of sample preparation and observed results by the electron microscopo were presented.
The failure energy of the epoxy-PSF matrices increased as the PSF content increased under all loading conditions, whereas the strength of the polymer blend matrices increased only under impact loading.
