Castor oil has been used to prepare millable elastomers by using 2,440luene diisocyanate, 4,4'-diphenylmethane diisocyanate, and 1,5naphthalene diisocyanate, re- spectively. These elastomers are vulcanized with sulfur and 4,4'-diphehylmethane diisocyanate separately by using the standard methods of rubber technology, and the properties of these vulcanizates are reported.

Castor oil, from Ricinus communis, has been used since ancient times as a safe and reliable laxative. The pharmacologically active molecule in the oil is ricinoleic acid. This hydroxylated, long-chain fatty acid has multiple effects on the intestinal mucosa, resulting in fluid secretion. Early studi
Coatings formulated from castor oil glycidyl ether (COGE), epoxy resin UVR 6100, and photoinitiator UVI 6990 produced smooth coatings with excellent gloss and good flexibility, adhesion, gloss retention, and water resistance. Formulations containing up to 50% COGE afforded promising coating performa
