According to the invention, there is a method for producing an acrylate-based solid, comprising the steps of: (i) dispersing less than 20% w/v of an alkyl or aryl acrylate polymer/copolymer in a solvent comprising at least one acrylic monomer; (ii) dispersing in the fluid mixture formed by step (i) a further quantity of an alkyl or aryl acrylate polymer/copolymer; and (iii) curing the resulting material to form a solid, Wherein the alkyl or aryl acrylate polymer/copolymer of step (i) contains less than 0.1% w/w of a free radical.
