A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Styrene/Acrylate/Divinylbenzene Copolymer (CAS 57516-68-4) is a styrene-acrylic copolymer crosslinked with divinylbenzene, commonly produced as insoluble polymer microspheres. The divinylbenzene crosslink yields rigid, solvent-resistant particles used as opacifying agents, bulking agents, and texturizers in coatings and personal-care formulations. The crosslinked network renders the polymer insoluble and dimensionally stable.
Frequently Asked Questions
What is styrene/acrylate/divinylbenzene copolymer?
Styrene/Acrylate/Divinylbenzene Copolymer (CAS 57516-68-4) is a styrene-acrylic copolymer crosslinked with divinylbenzene, commonly produced as insoluble polymer microspheres. It is used as an opacifying agent, bulking agent, texturizer, and structuring carrier particle in coatings and personal-care formulations.
What is styrene and divinylbenzene?
Styrene is the aromatic vinyl monomer that forms the polymer backbone; divinylbenzene is a difunctional monomer that crosslinks the chains. In this copolymer the divinylbenzene crosslink yields rigid, solvent-resistant particles that are insoluble and dimensionally stable.
Why is this copolymer insoluble?
The divinylbenzene crosslinks tie the polymer chains into a three-dimensional network rather than separate linear chains. That crosslinked network is what renders the polymer insoluble and dimensionally stable, allowing it to function as discrete microspheres for opacity and texture.
What is styrene/acrylate/divinylbenzene copolymer used for?
Its polymer microspheres scatter light to add opacity, provide volume and body as a bulking agent, modify feel and surface texture as a texturizer in coatings and cosmetics, and act as an insoluble crosslinked matrix for formulation structuring.
How is styrene/acrylate/divinylbenzene copolymer supplied in bulk?
We supply it to coatings and personal-care manufacturers in bulk packaging suited to the supplied form (powder or dispersion). CAS is 57516-68-4. Request a quote with your target volume and form for current bulk pricing, CoA, and SDS.
