 INTRODUCTION

Butadiene hydroxytelechelic oligomers (PBHT: polybutadiene hydroxytelechelic) are functional liquid macromolecules that enter polyurethane chemistry as constituent polyols.

They are distinguished from other polyols (polyesters or polyethers) by their unsaturated hydrocarbon skeleton, which gives the polyurethanes derived from them excellent resistance to hydrolysis, good cold flexibility and good dielectric properties.
