Abstract: NOVEL TERPOLYMERS ARE DISCLOSED COMPRISING TWO DIFFERENT A-OLEFINS AND AN ORTHOCONDENSED ISOPROPYLIDENECONTAINING POLYCYCLIC POLYENE HAVING THE FORMULS:

2-R1,3-R2,3A-R3,4-R4,1-(CH3-C(-CH3)=)-3A,4,7,7A-TETRAHYDRO

INDEN

2-R1,3-R2,4-R5,4A-R3,5-R4,1-(CH3-C(-CH3)=)-1,4,4A,5,8,8A-

HEXAHYDRONAPHTHALENE OR

1-R2,2-R1,3-(CH3-C(-CH3)=)-3,4,4A,5,8,8A-HEXAHYDRO

NAPHTHALENE

WHEREIN EACH OF SAID R'',R2,R3,R4 AND R5 IS H, METHYL OR ETHYL, PROVIDED AT LEAST ONE OF SID R1 OR R2 IS METHYL OR ETHYL, THE CONCENTRATION OF SAID POLYCYCLIC POLYENE IN THE TERPOLYMER BEING FROM 1 TO 30% BY WEIGHT AND THE MOLE RATIO OF SAID DIFFERENT ALPHA-OLEFINS BEING IN THE RANGE FROM 1:4 TO 4:1.
