SYNTHESIS AND CHARACTERISATION OF HYDROXY-TERMINATED POLYBUTADIENES
Abstract
An adaptation of the Szwarc 'living' polymer method was used to synthesise hydroxy-terminated polybutadienes up to 11,000 molecular weight which were characterised by infra-red and nuclear magnetic resonance spectroscopy. The latter technique indicates that the materials are predominantly 1,2-linked, and analysis by chemical and physical methods shows that the production of hydroxy-terminal groups is virtually quantitative. It is possible to react these polymers with 2,4-tolyene diisocyanate to yield thermoplastics, which can be crosslinked with castor oil to give good quality rubbers.
