Claim Text:
1. A method for reducing fouling in a hydrocarbon refining process comprising providing a crude hydrocarbon for a refining process; and wherein R y is an integer between 1 to 20 inclusive; m is an integer between 0 and 10 inclusive; a and b are C—C bonds in cis-configuration with respect to each other and in either cis- or trans-configuration with respect to bond c; R R wherein R 91 is a branched or straight-chained C 10 -C 800 alkyl or alkenyl group, the asterisk (*) indicates a connecting point with R 8 , d and e are C—C bonds in cis-configuration with respect to each other and in either cis- or trans-configuration with respect to bond f, and z is an integer between 1 to 20 inclusive; or (b) R 8 and R 9 together are a C 1 -C 4 branched or straight chained alkyl group optionally substituted with one or more amine groups; and wherein the —N(R 31 )—R 3 — repeat unit is optionally interrupted in one or more places by a nitrogen-containing heterocyclic cycloalkyl group; wherein R wherein R 71 is a branched or straight-chained C 10 -C 800 alkyl or alkenyl group, the asterisk (*) indicates a connecting point with R 6 , g and h are C—C bonds in cis-configuration with respect to each other and in either cis- or trans-configuration with respect to bond j, and q is an integer between 1 to 20 inclusive; or (c) a bond connected to R 31 in the m-th —N(R 31 )—R 3 — repeat unit.
