"PROCESS FOR THE PREPARATION OF MANNICH ADDICTS CONTAINING POLYISOBUTENYLPHENOL., MANNICH ADULT, USE OF AN ADDITIVE CONCENTRATED MANNICH ADULT, COMBUSTIBLE COMPOSITION, LUBRICATING COMPOSITION, AND, USE OF A COMPOSITION COMPOSITION." The invention relates to a method for producing Mannich adducts, which contain polyisobutylene phenol: a) by alkylating a phenol with highly reactive polyisobutylene, at a temperature lower than approximately 50 198 C and in the presence of a catalyst alkylation; b) by reacting the reaction product of a) with b1) an aldehyde, selected from formaldehydes, with an oligomer and with a formaldehyde polymer and with b2) at least one amine that has at least one primary or secondary amino function. The invention also relates to Mannich adducts that can be obtained using this method, to the use of Mannich adducts as detergent additives in combustible compositions and lubricating compositions, and to additive concentrates, combustible compositions and lubricating compositions containing these adducts of Mannich.
