    Abstract: An acylated polyamine polymers (I) are new. New acylated polyamine polymers (I) comprise acyl groups of formulas -CO-R (i) or -CO-R (ii) on some of the nitrogen atoms of the polyamine (I). R = 7-27C alkyl, 7-27C alkenyl or 7-27C hydroxyalkyl; and R = H, 1-6C alkyl or 1-6C hydroxyalkyl. Independent claims are also included for: (1) the preparation of (I) by reacting a polyamine with at least one carboxylic acid of formula R -COOH and at least one carboxylic acid of formula R -COOH or their esters, anhydrides or halogenated derivatives; (2) the preparation of (I) by cationic ring opening polymerization of: (a) at least one 4,5-dihydro-oxazole and/or 5,6-dihydro-4H-1,3-oxazine, both substituted with R on position 2; and (b) at least one 4,5-dihydro-oxazole and/or 5,6-dihydro-4H-1,3-oxazine, both substituted with R on position 2; and (c) optionally at least one other comonomer; (3) an aqueous composition comprising at least one acylated polyamine (I); (4) a method for increasing the viscosity of a composition containing surfactants by adding (I).
