A method of preparing a polymer comprises the use of free radical vinyl polymerisation to form carbon-carbon backbone segments of the polymer, wherein the longest chains in the polymer comprise vinyl polymer chains interspersed with other chemical groups and/or chains. The product has the characteristics of a step-growth polymer comprising a mixture of polyfunctional step-growth monomer residues formed by vinyl polymerization.

A method of solid-state synthesis of peptides that provides a polymeric solid-state synthesis support, attaches a first amino acid to said support to form the first amino acid molecule of the desired peptide chain, attaches additional amino acids to form the desired peptide chain, characterized in that the polymeric solid-state synthesis support is a styrenic polymer containing at least 50 mol % divinylbenzene monomer units, the styrenic polymer being functionalized with chloromethyl and/or benzyloxybenzyl alcohol and/or amino moieties, and having porosity 60-90% and medium pore diameter ranging from 10 to 80 nm. A functionalized styrenic polymer is claimed.
