Abstract
AbstractThe properties of polymer emulsions are described in which styrene is copolymerised with a range of acrylic esters, together with a minor quantity of acrylic acid. Properties examined included viscosity and minimum temperature of film formation of the emulsions, and the brittle point, rigidity modulus, tensile strength at maximum elongation, and elongation of the air‐dried films. The increase in chain length of the alkyl ester and the quantity of acrylate comonomer both gave more flexible and softer polymers. While approximately equivalent properties may be obtained by replacing one acrylate comonomer by an appropriate quantity of another, each copolymer is unique in its combination of properties.
