Abstract: NOVEL POLYMERS ARE DISCLOSED WHICH COMPRISE MODIFIED OLEFINS CONTAINING IN THEIR MOLECULE AN ENDOMETHYLENE RING OR A CYCLOALIPHATIC RING, A STRAIGHT HYDROCARBON CHAIN AND CHARACTERISTIS POLAR GROUPS INCLUDING COOH, CN, CHO, CONH2, SO3H, CH2,CI AND COOR* WHERE R* MAY BE AN ALKYL OR AN ARYL RADICAL. THE NEW OLEFIN POLYMERS ARE OBTAINED BY A DIELS-ALDER REACTION BETWEEN OLEFIN POLYMERS CONTAINING CONJUGATED DOUBLE BONDS WITH DIENOPHYL REAGENTS HAVING AT LEAST ONE OF THE ABOVE-MENTIONED CHARACTERISTIC FUNCTIONAL GROUPS AND TO THE MIXES OBTAINED THEREBY WHICH CAN BE CROSS-LINKED WITHOUT SULFUR.
