Abstract
An acrylic polymer gel suitable for use as a carrier in the controlled synthesis of polypeptides is provided. The polymer comprises a diazotized terpolymer of the condensation product of a monomer selected from the group consisting of hydroxyalkyl acrylates and hydroxyalkyl methacrylates, a polyfunctional cross-linking monomer selected from the group consisting of alkylene diacrylates, alkylene dimethacrylates, polyacrylates and polymethacrylates of polyalcohols, alkylene bisacrylamides and divinylbenzene, and an aromatic ring-containing compound selected from the group consisting of aromatic acids and their anhydrides and chlorides, aromatic isocyanates, halogenophenylsilanes, and aromatic epoxy compounds. The condensate has its aromatic rings chlormethylated. The first monomer and the polyfunctional cross-linking monomer are copolymerized and the resultant copolymer is condensed with said compounds which contain an aromatic ring.
