“…Therefore, the rubber content played a key role in the brittle‐ductile transition. Of course, the particle size was also an important factor . However, in this article, the rubber particle size was substantially constant because the same seed rubber was used in all graft copolymer.…”

Acrylonitrile‐styrene‐butyl acrylate (ASA) graft copolymers with different acrylonitrile (AN) contents, the core‐shell ratio, and tert‐dodecyl mercaptan (TDDM) amounts were synthesized by seed emulsion polymerization. Polyvinylchloride (PVC)/ASA blends were prepared by melt blending ASA graft copolymers with PVC resin. Then the toughness, dynamic mechanical property, and morphology of the PVC/ASA blends were investigated. The results indicated that the impact strength of the PVC/ASA blends increased and then decreased with the increase of the AN content in poly(styrene‐co‐acrylonitrile (SAN) copolymer, and increased with the increase of the core‐shell ratio of ASA. It was shown that brittle‐ductile transition of PVC/ASA blends was dependent on poly(butyl acrylate) (PBA) rubber content in blends and independent of AN content in SAN copolymer. The introduction of TDDM made the toughness of PVC/ASA blends poor. Dynamic mechanical analysis (DMA) curves exhibited that PVC and SAN copolymers were immiscible over the entire AN composition range. From scanning electron microscopy (SEM), it was found that the dispersion of ASA in PVC/ASA blends was dependent on the AN content in SAN copolymer and TDDM amounts. J. VINYL ADDIT.

On the Size of RVE in Finite Elasticity of Random Composites

2006

This paper presents a quantitative study of the size of representative volume element (RVE) of random matrix-inclusion composites based on a scale-dependent homogenization method. In particular, mesoscale bounds defined under essential or natural boundary conditions are computed for several nonlinear elastic, planar composites, in which the matrix and inclusions differ not only in their material parameters but also in their strain energy function representations. Various combinations of matrix and inclusion phases described by either a neo-Hookean or Ogden function are examined, and these are compared to those of linear elastic types.

“…Some authors Downloaded by [UNSW Library] at 01: 24 17 August 2015 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 4 have described approaches for improving the toughness of PBT by the reaction of a polymer containing an appropriate chemical functionality with the carboxyl or hydroxyl end groups of PBT during melt processing. [21][22][23][24] In the literature [25][26][27][28][29][30][31] polyolefins and elastomers containing various functionalities, such as maleic anhydride, epoxides, acids, isocyanate, and oxazolines, used to reactively compatibilize PBT have been reported; these reports evaluated the compatibilization efficiency of the different functionalities. The results showed that epoxy groups appeared to be more effective in PBT blend modification than the other functional groups.…”

Butadiene glycidyl methacrylate-functionalized-methyl methacrylate (PB-g-MG) core-shell copolymer was used to toughen poly(butylene terephthalate) (PBT). Fourier transform infrared spectra and torque tests showed that compatibilization reactions took place between the carboxyl and/or hydroxyl groups of PBT and the epoxy groups of PB-g-MG. Phase morphology results showed that the PB-g-MG core-shell particles dispersed in the PBT matrix uniformly. The addition of PB-g-MG significantly improved the mechanical properties of PBT. The elongation at break and the impact strength increased with the increase of PB-g-MG content. SEM resultsshowed that the shear yielding properties of the PBT matrix was the main toughening mechanism.The relationship between complex viscosity and angular frequency of the PBT/PB-g-MG blends indicated that the melt viscosity was higher than that of pure PBT.
