Abstract

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.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 119 words
A polymeric gel carrier having a macroporous structure for use in the controlled synthesis of polypeptides, comprising a diazotized terpolymer of a first monomer selected from the group consisting of hydroxyalkyl acrylates, hydroxyalkyl methacrylates, aminoalkyl acrylates and aminoalkyl methacrylates, a polyfunctional cross-linking monomer selected from the group consisting of alkylene diacrylates, alkylene dimethacrylates and polyacrylates and polymethacrylates of polyalcohols and a third monomer which contains an aromatic ring selected from the group consisting of phenyl acrylate, phenyl methacylate, phenoxyalkyl acrylates and phenoxyalkyl methacrylates, at least one of said monomers being an amino-containing monomer, said latter terpolymer being coupled with a passive aromatic component selected from the group consisting of phenolic compounds and thereafter having the aromatic rings thereof chloromethylated.
Claim 2
Dependent Claim 119 words
