Toughness and Transparency of Poly(vinyl chloride)/Methyl Methacrylate-Butadiene-Styrene Blends with Varied Shell Phase Composition of Core-Shell Theories

Abstract

Methyl methacrylate-butadiene-styrene (MBS) were prepared by emulsion polymerization method through grafting of styrene (St) and methyl methacrylate (MMA) with varied ratio on polybutadiene (PB) particles. The effect of St/MMA weight ratio of the shell in MBS on the property of PVC/MBS blends was investigated. It was found that when St/MMA weight ratio was 0/40 and 10/30, brittle-ductile transition occurred firstly for PVC/MBS blends. Transparency of PVC/MBS blends enhanced with the increase of St content in the shell of MBS. TEM results showed that MBS composition in the shell affected disperse morphology of MBS particles in PVC matrix and the deformation behavior of PVC/MBS blends. With the increase of MMA content of the shell in MBS, the deformation mechanism of PVC/MBS blends take place transition from debonding in the interface between MBS particle and PVC matrix to the cavitation of MBS followed by shear deformation of PVC matrix.

The Relation Between Particle Structure and the Peel Strength of Vinyl Acetate/Acrylate Core-Shell Latexes Laminating Adhesives

“…In recent years, the core-shell emulsion prepared by multistage polymerization is gradually attracting substantial attention [17][18][19][20][21][22][23][24][25][26][27] because of its some more excellent performances over conventional emulsion, such as lower minimum film formation temperature [28] (MFT), greater control of particle size [29] . etc.…”

Miscibility and thermal and mechanical properties of melt‐mixed poly(lactic acid)/poly(trimethylene terephthalate)/(methyl methacrylate)‐butadiene‐styrene copolymer blends

“…PLA also has a chemical structure like that of PMMA. So in this article, we consider the evaluation of MBS, which is one of the most efficient impact modifiers for poly(vinyl chloride) [15, 17–21, 24–28], as an impact modifier of PLA and PLA/ PTT blend in order to enhance their applications in films, engineering thermoplastics, and molded goods.…”

Agglomeration of the poly(butadiene‐styrene) latex triggered by CO2bubbling and the preparation of poly(methyl methacrylate‐butadiene‐styrene) core/shell particles with a wide size distribution

“…Thus, the agglomerating technology is extremely vital to the preparation of impact modifiers with a wide size distribution. Unfortunately, most of the investigations were concentrated on the effect of particle size, core/shell ratio, shell thickness, arrangement of compositions and internal structure of MBS particles on the MBS/PVC blends [16][17][18], few literatures focused on the exploration of an efficient and economic agglomeration technology and the preparation of MBS latex particles with a wide size distribution.…”
