A method for removing aromatic compounds from a hydrocarbon fluid comprises contacting the hydrocarbon fluid with a solid-phase polymeric material. The solid-phase polymeric material comprises a cross-linked polymer which contains aromatic groups. The method may be used to prevent the build-up of sludge and soot in a lubricant system in an internal combustion engine. A polymer bead comprising a solid-phase polymeric material is also provided.

Removing aromatic compounds from a hydrocarbon fluid

The present application is directed at the reaction product of an azide compound having two or more azide groups attached thereto and an alkyne compound having two or more alkyne groups attached thereto, wherein the azide and alkyne groups react in a 1,3-dipolar cyclo addition to form 1,4-disubstituted triazols and wherein the azide or alkyne compound or both include &#x2014;O&#x2014;(C&#x2550;O)&#x2014;NR&#x2014; functional groups. The reaction products can be used as coatings, such as for flat roofs, sealants, adhesives and in elastomer applications. Methods for producing the reaction products as well as substrates including a coating of the reaction product are also disclosed.
