ABSTRACT:
Synthesis of a vinyl terminated polymer by reacting a cationically polymerizable monomer in the form of a cyclic ether with an acid chloride in a suitable solvent and in the presence of a Lewis acid. The vinyl-terminated polymers can be polymerized with other appropriate monomers resulting in thermoplastic elastomers having suitable properties for use as binders for explosives and propellants.
