General structure of polyacrylates.

Polyacrylates (polyacrylic acid esters ) are polymers made from esters of acrylic acid ( acrylic acid esters ) . They are plastics that are used , among other things, in paints and as a dispersant for adhesives .

They are produced by radical chain polymerization in aqueous solutions, emulsions ( emulsion polymerization ) or by bulk polymerization with an end product as a powder.

The polyacrylates are often produced as copolymers , for example with esters of methacrylic acid . In general, the most varied properties of these polymers can be adjusted within a very wide window by copolymerization. The polyacrylates can be divided into high and low molecular weight polymers.

Polyacrylate rubber is a synthetic rubber that consists of acrylic acid alkyl ester ( ethyl or butyl ester) and is resistant to heat and mineral oils .

Monomers for polyacrylates

The following is a list of monomers that are used in polyacrylates for use in varnishes and paints.

Monomers as acrylic esters without any further functional group:

Monomers as methacrylic esters without any further functional group:

Monomers with other functional groups:

Monomers which are neither based on acrylic acid nor methacrylic acid, but are used in polyacrylate resins (comonomers):
