Abstract
An olefinic-terminated polyalkadiene that includes carboxy ester linking groups and at least one nascent secondary hydroxyl group that is capped with a monoisocyanate. This polyalkadiene can be made by reacting a hydroxyl-terminated polyalkadiene with a saturated cyclic acid anhydride to form a carboxylic acid-terminated polyalkadiene, reacting the carboxylic acid-terminated polyalkadiene with an olefinic monoepoxide to form an olefinic-terminated polyalkadiene, then reacting the olefinic-terminated polyalkadiene with a monoisocyanate.
