Question
I have a highly technical question regarding the material Styrene/Acrylates Opacifier (e.q. OP301). Could you please provide information on the following points?
- Where do you source your styrene from?
- Where does the acrylic acid that is reacted with the styrene and an ester (to make the styrene acrylates copolymer) come from?
- Do you know what reaction type is used to make these polymers?
Answer
Thank you for your technical questions regarding the Styrene/Acrylates Opacifier (e.q. OP301).
The specific details you are asking about—the source of the raw materials (styrene and acrylic acid) and the exact reaction type used by the manufacturer—are considered proprietary and confidential information. This level of detail is not provided in the standard product documentation (such as the Product Description or Certificate of Analysis) we receive from the producer.
However, we can provide some general chemical context:
- Sourcing of Styrene and Acrylic Acid: The specific origin (country or supplier) of the raw monomers is proprietary. Both styrene and acrylic acid are widely produced petrochemical derivatives.
- Reaction Type: The Styrene/Acrylates Copolymer used in this opacifier is supplied as an aqueous dispersion (as indicated by the INCI: Styrene/Acrylates Copolymer, Water). The most common and industry-standard method for producing these types of polymer dispersions is Emulsion Polymerization. This process involves polymerizing the monomers (styrene, acrylic acid, and potentially an ester monomer) in water using a surfactant and an initiator.
