Styrene-methyl methacrylate SMMA

There are a wide range of applications that are made from SBC that may show up in the ordinary household. Some SBCs are used in appliances, housewares and office supplies. Owing to limitations of temperature resistance, chemical resistance, and abrasion resistance, the SBC may be blended with polymers such as styrene-methyl methacrylate (SMMA) to improve functionality. SBCs may also be seen in parts such as aquarium filter tanks, sewing machine dust covers, bird feeders, cake pan lids, pens, vacuum cleaners and computer accessories. [Pg.518]

Another promising area of growth is for SBC blends with higher-performing styrenics such as styrene-methyl methacrylate (SMMA) and SAN, in order to down-engineer applications currently in higher-cost PC, acrylic, or clear ABS. Potential uses include molded appliance parts and medical devices and extruded graphic display profiles. [Pg.1765]

The utility of the runaway and sensitivity parameters a,B, and b has been demonstrated through both numerical simulation and experimentation (3, h) Numerical simulations employed literature values for the kinetic constants for the monomer pairs of Styrene-Methyl Methacrylate (SMMA), Styrene-Acrylonitrile (SAN) and, AcrylonItrIle-Methyl Methacrylate (ANMMA). Phi-factor kinetics were generally used, however both geometric mean and recently-advanced penultimate effect kinetics (6) were tested as well. Experiments were confined to the Styrene-Acrylonitrile comonomer system, however, the full range of compositions was studied. An extensive initial rate study was performed on this system to develop the kinetic constants needed to evaluate the runaway parameters. ... [Pg.175]

Homogeneous blends of a thermoplastic styrene/methyl methacrylate (SMMA) copolymer and a thermoplastic vinylidene fluo-ride/hexafluoropropylene copolymer which is an excellent processing additive for the extrusion of thermoplastic polyolefin (1). [Pg.115]

Another polymer that has been very successful in blends with SBC is polystyrene-methyl methacrylate (SMMA), a styrene acrylic copolymer. Compared with SBC, SMMA offers significantly higher stiffness, surface hardness and temperature resistance. The refractive index of these copolymers can be... [Pg.521]

In 1983, Monsanto developed blends with co-continuous morphology, Triax 2000. These alloys comprised PC, ABS, and styrene-methylmethac-rylate-maleic anhydride (SMMA-MA) [Jones and Mendelson, 1985]. One year later, PC was reactively blended with either ABS, SAN-GMA, and NBR, or with graft copolymers of acrylonitrile-butadiene-a-methyl styrene-methyl-methacrylate (MeABS) and acryloiutrile-a-methyl styrene-methyl methacrylate copolymer (MeSAN) [Kress et al., 1986]. The blends were commercialized by Bayer as Bayblend . [Pg.33]

Figure 3.5 Experimentally determined fractions of methyl methacrylate in the droplet phase as a function of the fraction of methyl methacrylate in different latex particles. Methyl methacrylate and styrene in polybutadiene (open circles), SMMA-free (open squares), SMMA-graft (open triangles) from polybutadiene-graft-poly(styrene-co-methyl methacrylate) latex particles, while the closed squares represent a poly(styrene-co-methyl methacrylate) latex swollen with styrene and methyl methacrylate. The solid line gives the theoretical prediction according to Equation 3.13.
