A synthetic resin based on a polystyrene that can be used as a support for solid phase peptide synthesis and that has been cross-linked with from 0 to 5 mol % of divinyl benzene, characterized in that it has been substituted at benzene rings of its skeletal structure by groups of the formula ##STR1## in which X represents --O-- or --NH-- and R represents C.sub.1 -C.sub.4 -alkyl, as a support renders possible the solid phase synthesis of peptides and peptide amides that are, if desired, protected at the N-terminal and/or at other functional groups. The resin is manufactured by reaction of a customary chloromethylated polystyrene resin with an alkali metal salt of the corresponding 4-hydroxybenzophenone and subsequent reduction of the carbonyl group and, optionally, amination.
