The present disclosure relates to a method of immobilizing a phenolic compound having a Mw ≥ 500 g/mol, wherein the method comprises the steps of ionizing the phenolic compound by subjecting it to a base; and contacting, under agitation, the ionized phenolic compound with a cross-linked resin comprising the functionality of -C(=0)- CHXCH2R, wherein X is chosen from the group consisting of Br, Cl, I, CN, OMs, OTs, or OTf, and R is H, CH3 or an branched or unbranched alkyl having 1 to 8 carbon atoms, in the presence of a base and a solvent. The present disclosure also relates to a method of removing phenolic compounds having a Mw ≥ 500 g/mol from a composition comprising compounds having at least one alkoxy silane group. The present disclosure also relates to the use of a method according to the present disclosure as well as to a product, from which at least one phenolic compound having a Mw ≥ 500 g/mol has been removed by a method according to the present disclosure.
