ABSTRACT:
Polytetrahydrofurans containing terminal acrylate or methacrylate groups and having a molecular weight of from 200 to 10,000 and a process for producing such polytetrahydrofurans by homopolymerizing tetrahydrofuran, optionally in an organic solvent, together with acrylic acid anhydride and/or methacrylic acid anhydride and with the aid of a catalyst. The polytetrahydrofuran can be used as rubbers.
