Hydrohalogenation of vinyl terminated polymers and their functionalized derivatives for fouling mitigation in hydrocarbon refining processes

A compound represented by

• wherein R1 is a branched or straight-chained C10-C800 alkyl or alkenyl group;
• m is an integer between 1 and 10 inclusive;
• R2 is represented by
• or —CH2—CH2—CH2—*, wherein the asterisk (*) indicates a connecting point of R2 with the nitrogen that connects with R3;
• R3 is a C1-C4 branched or straight chained alkylene group;
• R31 is hydrogen or —R8—R9, wherein R8 is defined the same as R2 above, and R9 is branched or straight-chained C10-C800 alkyl or alkenyl group, or R8 and R9 together are a C1-C4 branched or straight chained alkyl group optionally substituted with one or more amine groups;
• and further wherein the —N(R31)—R3— repeat unit is optionally interrupted in one or more places by a nitrogen-containing heterocyclic cycloalkyl group;
• and
• R4 and R5 are each independently selected from (a) hydrogen, (b) —R6—R7, wherein R6 is defined the same as R2 above, and R7 is a C10-C800 branched or straight chained alkyl or alkenyl group, or (c) a bond connected to R31 in the m-th —N(R31)—R3— repeat unit;
• wherein at least one of R1, R7, and R9 comprises poly(ethylene-co-propylene), and wherein the at least one of R1, R7, and R9 comprises from about 1 mole % to about 90 mole % of ethylene units and from about 99 mole % to about 10 mole % propylene units.
