摘要：
Y-Z(-(Y'')N)(-(R'')H)-X
WEHEREIN X IS AN ATOM OF HAOLGEN, Z IS NITROGEN, CARBON OR PHOSPHOROUS; R'' IS HYDROGEN RADICAL WITH FROM 1 TO 10 CARBON ATOMS, OR HYDROGEN, OR IS EQUAL TO X; Y IS A MEMBER OF THE GROUP CONSISTING OF
-SO2-R", -CO-R", -COO-R", -P(=O)(-R")2,
(R")2-N-C(=N-R")-, -C(=S)-R", -C(=S)-O-R", -C(-R")2-NO2
-C(-R")2-CN, -N=C=O, =C(-R")-NO2, -C(-R")=N, =C(-CL)-R"
1. PROCESS FOR THE PRODUCTION OF BUTYL RUBBER THROUGH THE COPOLYMERIZATION OF ISOBUTYLENE AND ISOPRENE WHEREIN THE IMPROVEMENT COMPRISES CONDUCTING THE COPOLYMERIZATION REACTION IN THE PRESENCE OF A CATALYTIC SYSTEM CONSISTING ESSENTIALLY OF: (A) A METALORGANIC COMPOUND OF ALUMINUM HAVING THE FORMULA AIR3 OR AIR2X WHERE X IS A HALOGEN ATOM AND R IS A HYDROCARBON RADICAL WITH FROM 1 TO 10 CARBON ATOMS, OR HYDROGEN; AND (B) A COMPOUND CONTAINING A MOBILE HALOGEN GROUP OR AT LEAST ONE IN WHICH THE HALOGEN GROUP IS EASILY EXCHANGEABLE DUE TO THE PRESENCE OF AN ELECTROPHILIC GROUP REPRESENED BY THE FORMULA
Y'' IS EQUAL TO Y, OR TO R''; Y OR Y'' MAY BE A BIVALENT RADICAL LINKED THROUGH A DOUBLE BON DIRECTLY TO Z; Y AND Y'' MAY BE CONNECTED TO EACH OTHER CLOSING THEMSELVES CYCLICALLY ON Z; R'''' IS AN ALKYLIC OR ARYLIC RADICAL, SIMPLE OR SUBSTITUTED; N AND H ARE 0 OR 1.
