S U G G E S T E D USES 1. Coatings. Derivatives of dicyclopentenyl alcohol, particularly its esters with u n s a t u r a t e d acids, such as t h e m e t h a c r y l a t e or linoleate, and i t s mixed esters, such a s allyl dicyclopentenvl maleate, have interesting air-drying and polymerizing properties. I n general, the dicyclopentenyl group contributes toughness and hardness, with improvement in water and alkali resistance. 2. Other Uses, Dicyclopentenyl alcohol m a y b e of interest in the p r e p a r a t i o n of derivatives for use in the fields of plasticizers, insecticides, oil additives, surface-active agents and solvents.
