Styrene/Acrylate copolymers are based on a group of chemicals that are true workhorses in the field of polymer chemistry.
Known as acrylates, this group includes acrylic acid and its esters — methyl acrylate, butyl acrylate, ethyl acrylate, and 2-ethylhexyl acrylate.
All of these acrylic monomers are highly reactive chemicals, which means they readily combine with themselves or other monomers to form commercially important polymers.
One of the most important polymer reactions, occurring via emulsion polymerization, involves acrylic-based monomers combining with styrene to form a styrene-acrylic emulsion polymer.
The versatility of this class of polymers owes much to the wide-ranging family of acrylic monomers, which, when combined with styrene, can build random copolymers with specific glass transition temperatures (Tg).
Styrene-acrylic polymer emulsions are ubiquitous in every market where water-based systems are used because of the array of specific properties that can be achieved.
