Filed: 1990-12-24
Abstract: UNSATURATED POLYLACTONES AND DERIVATIVES THEREOF                     ABSTRACT Novel unsaturated polylactones are produced by the reaction of an unsaturated alcohol, such as tetrahydrobenzyl alcohol, with a lactone.  Said product may be subsequently epoxidized to form unique polylactone epoxides.  Also, the unsaturated polylactones may be derivatized with isocyanates, anhydrides, and carboxylic acids and epoxidized to form useful modified polylactone epoxides.  The novel compounds of this invention are useful in coating, ink, adhesive, or sealant formulations, as well as useful as intermediates in the production of other valuable compounds, and in other end uses.
