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.

Abstract: New, readily curable, amorphous terpolymers are disclosed which are prepared from ethylene, propylene and a polyene hydrocarbon which contains two double bonds and is represented by the formula:

Abstract translation: 公开了新的，易固化的无定形三元共聚物，其由乙烯，丙烯和含有两个双键并由下式表示的多烯烃制备：A' - （C（R））n - （CH）m B' 其中A'是含有具有内亚甲基的环的基团; B'是一个二烯基团; Ro可以是氢，芳基或烷基; n是从0到3的整数，m是0和1，如果n不同于0，则m是0，而如果n是0，则m可以都是0和1。
