STYRENE ACRYLIC COPOLYMER EMULSION (CAP: 1960 KG./DAY)
[EIRI/EDPR/4496] J.C.: 2712INR, 2712US$
INTRODUCTION
Styrene-acrylic emulsion polymers 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.
In addition to versatility, cost is another significant advantage. The price of styrene is lower than chemicals found in the acrylate family. That makes styrene-acrylic polymers cost-effective alternatives to pure acrylics.
Styrene-acrylic polymers offer excellent hydrophobic characteristics, which means they have superior water resistance and moisture vapor transmission rate (MVTR) when compared to all-acrylic polymers. Also, styrene itself is a hydrophobic monomer, making it possible to produce styrene-acrylic polymers with low particle sizes. This results in polymers that are ideal for certain applications, such as primers for the construction industry or binders for paper coatings.
