Abstract
Abstract WHEREIN R2, n and A have the same meaning as above. The new polyacrylates are valuable resins which can be polymerised by themselves or together with other polymerisable monomers, whilst being shaped. The resulting mouldings or coatings display good mechanical properties. wherein Z represents a divalent radical required to complete a five-membered or six-membered ring, are obtained if n mols of acrylic acid and/or methacrylic acid are added onto polyglycidyl compounds of the formula New polyacrylates of the formula wherein R1 and R2 denote a hydrogen atom or the methyl group and n denotes the number 2 or 3 and A denotes an organic radical which contains at least one grouping
