Styrene maleic anhydride (SMA or SMAnh) is a synthetic polymer that is built-up of styrene and maleic anhydride monomers. In one copolymer, the monomers can be almost perfectly alternating. [1] but (random) copolymerisation with less …

Styrene-maleic anhydride copolymer, a thermoplastic resin produced by the copolymerization of styrene and maleic anhydride. A rigid, heat-resistant, and chemical-resistant plastic, it is used in automobile parts, small appliances, and food-service trays.

Amongst copolymer-type compatibilizers, styrene–maleic anhydride copolymers (SMA) is the most commonly used for PA6/PPE blends [32,33,34,35]. Low-priced monomers and facile synthesis via radical polymerization enable a broad commercial availability of SMA, having different MA concentrations.

2019年1月1日 · The copolymers are synthesized as styrene-maleic anhydride (SMAnh), and need to be converted to the free acid form (SMA) before they are capable of solubilizing membranes. This hydrolysis reaction is traditionally performed under rather cumbersome reflux conditions.

2015年12月6日 · Copolymers of styrene and maleic acid/anhydride: chemical structure, applications, and availability. Styrene–maleic acid (SMA) is the hydrolyzed form of the styrene–maleic anhydride (SMAnh) copolymer, which is synthesized by the copolymerization of styrene and maleic anhydride monomers (Fig. 2, Reaction 1). Both forms of the polymer are ...

The SMA copolymer, used for this study, is a low molecular weight styrene maleic anhydride copolymer with ca. 2:1 mole ratio of styrene to maleic anhydride. Upon hydrolysis, the maleic anhydride is converted into the hydrophilic maleic acid rendering the copolymer amphiphilic.

Styrene – maleic anhydride copolymers are highly interesting functional polymers. Commercially available polymers over a wide range of molar mass and chemical composition are used for a wide variety of applications.

The copolymerization of styrene and maleic anhydride has received significant attention in academia as well as in industry. Nevertheless, the underlying mechanism of the copolymerization is still a point of debate. In this paper, an overview is given that provides compelling evidence in favor of the penultim

2020年7月29日 · In this paper, we report for the first time the self-stabilized precipitation polymerization of styrene (St), maleic anhydride (MAH), and acrylamide (AM) in isoamyl acetate as the reaction medium.
