Abstract
A compound useful for reducing fouling in a hydrocarbon refining process is provided. A method for preparing the compound includes hydrohalogenating a polymer having a vinyl chain end to obtain a halogen-containing terminal group, and reacting the terminal group with a polyamine. Methods of using the compound and compositions thereof are also provided.
