    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.

    Abstract: A NEW CURABLE AMORPHOUS TERPOLYMER HAVING A HIGH CURING RATE, WHICH CONSISTS OF TWO ALPHA OLEFINS, E.G., ETHYLENE AND PROPYLENE, AND A POLYENE HAVING TWO CONJUGATED DOUBLE BONDS AND REPRESENTED BY THE FORMULA:

    1-R1,2-(R"''-(R"-)C=C(-R'')-),3-R,4-R4,5-R3,6-R2-NORBORNA-

    2,5-DIENE

    WHEREIN R IS H OR ALKYL AND R1, R2, R3, R4, R'', R" MAY BE H, ALKYL OR ARYL, IS PREPARED BY POLYMERIZING THE TWO ALPHA OLEFINS AND THE POLYENE IN THE PRESENCE OF A COMPOUND OF A TRANSITION METAL OF GROUPS IV TO VIII OF THE PERIODIC TABLE AND A REDUCING ALUMINUM COMPOUND REPRESENTED BY THE FORMULA:

    AIROX1X2.NZ

    WHEREIN RO IS H OR A HYDROCARBON RADICAL HAVING 1 TO 10 C ATOMS; EACH OF X1 AND X2, WHICH MAY BE THE SAME OR DIFFERENT, IS H, AN HYDROCARBON RADICAL HAVING 1 TO 10 C ATOMS HALOGEN OR A SECONDARY AMINE RADICAL; Z IS A LEWIS BASE; AND N IS 0-2.
