Claim 1
Independent Claim
104 words
A NORMALLY SOLID, CURABLE COPOLYMER OF (1) ETHYLENE; AND (2) AT LEAST ONE HALOGENATED OLEFIN SELECTED FROM THE GROUP CONSISTING OF: (A) COMPOUNDS HAVING THE STRUCTURE CH2=CH-CH2-R WHERE R IS A MONOVALENT ALIPHATIC HYDROCARBON RADICAL HAVING FROM ABOUT 1 TO 12 CARBON ATOMS, SAID RADICAL BEING SUBSTITUTED BY AT LEAST ONE HALOGEN ATOM; AND (B) 2-NORBORNENES SUBSITITUED IN AT LEAST ONE OF THE 5- AND THE 6-POSITIONS WITH HALOGEN-BEARING HYDROCARBON RADICALS HAVING NO MORE THAN 5 CARBON ATOMS, THE DOUBLE BOND AT THE 2-POSITION BEING UNSUBSTITUTED; SAID COPOLYMERS CONTAINING AT LEAST 2% BY WEIGHT OF SIDE-CHAIN SUBSTITUTED HALOGEN, BASED ON THE WEIGHT OF COPOLYMER.
