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.

For the Polymer blend system of Poly (styrene-co-Methyl methacrylate) (PS-co-MMA)/phenolic resin (PR), there exists specific interaction of hydrogen bond between the polymer components. Therefore, it is possible to control the phase morphology by changing the composition of the copolymer and the blending ratio of the PS-co-MMA/ PR blend system.
Through selecting proper polymer blend system,the PVDF hollow fibre membrane with high performance,high porosity,hydrophilic surface could be prepared.
The morphology, network and mechanical properties of a polymer blend system(cis 1, 4 polyisoprene(IR) polychloroprene(CR) poly(styrene isoprene)) triblock copolymer (SIS) have been investigated by using various methods. Results show that 3￣7 portions (wt%) of SIS copolymer have obviously improved phase dispersion, increased the value of constants 2 C 1, 2C 2 and tensile strength of covulcanizates and decreased mechanical loss of the blends.
Direct measurement of the interfacial curvatures for a bicontinuous polymer blend system as well as real space measurement of structure in phase separating polymer mixtures are now possible using CLSM.
This paper investigated mechanism of electrical treeing inhibition in SBR/ LDPE (styrene butadiene rubber and low-density polyethylene) and HDPE/ LDPE (high-density polyethylene and low-density polyethylene) polymer blend system. The experimental results show that the physical blends (physical method) of the change of polymer morphology increase the treeing inc(?)ption voltage of polymer blend system (improve tr(?)eing resistant property of LDPE) and this is b...
Using a new system called microscope-television-camera system,the diffusion coefficients of polymer blend dopes during the static coagulation process were measured and calculaated,and the effect of polymer blend system on diffusion coefficients was studied.It was found that the diffusion coefficients of acrylic blend dopes were usually higher than those of acrylic dopes in 'DMF as well as in NaSCN aqueous solution.
In this paper, the two phase structure and some related biological properties were studied by using DDV and DSG measurements. It was found that there existed some interaction between the hard segment of polyurethane and polyacrylonitrile in this polymer blend system. The results from property measurements showed that the mould resistance of the blended polyurethane was much better than that of unblended ones. After hydrolysis in basic meduim,the hydrophilibility of the blended ...
