In the 1950 s, the core-shell, emulsion type methylmethacrylate-butadiene-styrene terpolymer (MBS) was developed to toughen PVC or PC. These blends could also contain other polymers, viz. SAA [Murdock et al., I960] SMM and PS [Murdock et al., 1962] SMM-AN [Schmitt et al., 1967] high heat ABS [Kanegafuchi Chemical Industry, 1967] HIPS [Ward, 1970] MMVAc-AA [Holland et al., 1970] SMMA [Blasius, 1992], etc. Table 1.34 traces evolution of these systems. Later, these multipolymers were modified by incorporation MA, AA, or GMA units to serve as reactive compatibilizers and toughening agents for PA, PEST or PC blends. [Pg.46]

In addition to ABS, with polybutadiene as the elastifying component, there is another forerunner among the polymer products formulated for low-temperature impact resistance, PVC-U. Elastifying ligands include EVAC, EVAC/VC graft polymer, PAEA C (polyacrylic acid ester/vinyl chloride copolymer), ACE (acrylic ester/MMA graft polymer) as well as the chlorinated low-pressure polyethylene PE-C in use for over 35 years. All of the polymer blends listed here are suitable for outdoor applications since they contain no unsaturated components. Polybutadiene-modified products are better suited to interior applications, for example MBS, a methylmethacrylate/butadiene/styrene graft polymer [55]. [Pg.124]

Since A and B are constants for a given copolymer and the possible temperature interval is relatively limited, a transition is predicted at an approximately constant shear stress. Melt transitions have in fact been reported at approximately constant shear stresses for styrene-butadiene-styrene triblock copolymers (4). However, this behavior was certainly not observed for the styrene methylmethacrylate diblock copolymer,... [Pg.536]

Predesigned particles of impact modifiers are based on core-shell technology. Core is involved in impact modification and shell improves adhesion between PVC and impact modifier particles.Three major combinations are used methacrylate-butadiene-styrene, MBS, which has a core made out of butadiene-styrene copolymers and shell made out of methylmethacrylate-styrene copolymer, acrylic impact modifiers, AIM, which have a core made out of acrylic and shell from polymethylmethacrylate, and silicone-acrylic have multilayer structures with silicone-acrylic in the core. MBS has excellent compatibility with PVC, similar to ABS, which is used as an impact modifier of PVC, as well. In both cases of ABS and MBS, weather resistance is lacking, therefore they are used for indoor applications only. At the same time, MBS gives translucent to crystal clear products, whereas with AIM, only translucent products are possible. In order to improve optical properties of AIM, it has to be reformulated. For transparent products, the core is made out of acrylic-styrene copolymers. Comparing silicone and all acrylic impact modifiers, PVC containing silicone-based products has superior low temperature impact properties. The incorporation of silicone into an acrylic impact modifier provides excellent weatherability, and thermal stability. It has shown improved retention of impact after outdoor weathering in PVC. ... [Pg.62]

PP has been blended with polyvinylchloride (PVC) for extrusion of pipes or electrical insulation [4]. The blends are compatibilized by addition of either methylmethacrylate-butadiene-st)TCne copolymer (MBS), a graft copolymer of acrylonitrile-butadiene-styrene-methylmethacrylate (ABSM), ethylene-vinylchloride copolymer (VCE), ethylene-vinyl-acetate-vinylchloride copol5oner (EVAc-VC), EVAc, etc. The blends also comprised other resin, viz. PE, PS or SBR, PMMA or PC, etc. [Pg.619]

The methylmethacrylate-alphamethylstyrene-acrylonitrile terpolymer system is an attractive component in compatible blends with acrylonitrile butadiene styrene (ABS). The compositional window of terpolymer and terpolymer miscibility is of interest during manufacture and during blending. The common monomers in the terpolymer A, terpolymer B are a-methylstyrene, acrylonitrile, and methyl methacrylate. The B... [Pg.62]

Commercial copolymers. Styrene-butadiene block copolymer (SBS), acrylonitrile-butadiene-styrene (ABS), styrene-acrylonitrile (SAN), styrene-methylmethacrylate (SMMA), and styrene-maleic anhydride (SMA) are important styrene copolymers. [Pg.639]

The impact on the PHRR when substituting a polymer oligomer as a surface treatment on montmorillonite for a quaternary ammonium ion is not a panacea [51,52]. The comparison of methylmethacrylate oligomer-treated montmorillonite with quat-treated montmorillonite in poly(methylmethacrylate), polystyrene, high-impact polystyrene, acrylonitrile-butadiene-styrene terpolymer, polypropylene, and polyethylene nanocomposites indicated sensitivity to polymer type and a poor correlation to the degree of exfoliation determined by X-ray analysis and TEM. The impact of polymer structure associated with the montmorillonite appears to be a significant variable relating to the PHRR of these composites. In this book, chapter 4 on barriers... [Pg.169]
