Polystryene can come in a few different forms:
Sep 01, 2015· Styrene-Acrylic Emulsion Polymers. Styrene-acrylic emulsion polymers are water based polymers that can be produced from styrene and various acrylate esters such as methyl methacrylate, butyl acrylate, 2-ethylhexyl acrylate, acrylic acid, etc. By selecting the appropriate hard (ie styrene) and soft monomers, polymers with specific attributes.
Styrene acrylates copolymer may contain a small amount of residual styrene. Styrene is used predominately in the production of polystyrene plastics and resins. Styrene is also used as an intermediate in the composition of materials used for ion exchange resins and to produce copolymers.
Styrene Butadiene Copolymer Resins Selection Styrene Butadiene Copolymers (SBC) represent a versatile family of resins for adhesive and sealant development. Formulations prepared with SBC resin as base polymer offer a unique combination of properties and have found wide applications in diverse markets.
Styrene is the simplest alkenylbenzene which is an unsaturated aromatic monomer. It is widely used as column packing material in liquid chromatography for separation of both organic and inorganic ions. Styrene-divinylbenzene Copolymer is used in inorganic trace analysis for solid phase extraction preconcentration.
Styrene-maleic-anhydride copolymers (SMA) are crystal clear, amorphous thermoplastic resins formed by free-radical copolymerization of styrene and maleic anhydride. SMA offers high heat and chemical resistance, high gloss and high reactivity (anhydride portion). Some impact-modified SMA grades also have excellent impact resistance.
Styrene Butadiene Copolymer Resin Fundamentals The simplest block copolymer can be visualized as a rubbery elastomeric midblock with one or two thermoplastic (styrene) endblocks . This is illustrated in figure below where the green diamond like structures represent the thermoplastic endblocks and the circles represent the rubbery midblock.
A copolymer is a polymer derived from more than one species of monomer. The polymerization of monomers into copolymers is called copolymerization. Copolymers obtained by copolymerization of two monomer species are sometimes called bipolymers. Those obtained from three and four monomers are called terpolymers and quaterpolymers, respectively. Commercial copolymers include acrylonitrile butadiene styrene, styrene/butadiene co-polymer, nitrile rubber, styrene-acrylonitrile…
