Provided are: a graft copolymer which can be safely and stably produced with simple operation, while maintaining the characteristics of an amine, and which is lower in the introduction cost than conventional graft copolymers; and a method for producing the graft copolymer. A polyamine graft polymer that is obtained by polymerizing a polyamine derivative, which is obtained by reacting a polymer compound (a) having at least one amino group with a compound (b) having at least one epoxy group, with an ethylenically unsaturated monomer (c). A method for producing a polyamine graft polymer, which comprises a step for adding, for polymerization, an ethylenically unsaturated monomer (c) and a radical polymerization initiator to a polyamine derivative, which is obtained by reacting a polymer compound (a) having at least one amino group with a compound (b) having at least one epoxy group, in a polar solvent.

Novel polymers comprising polyolefin-substituted amines grafted with aromatic N-containing monomers such as aniline, have been found to provide oil soluble polymers which have dispersant and antioxidant properties in oleaginous compositions, including fuel and lubricating oils, and also which are useful in electrical applications. These materials are formed by a process which comprises: (a) contacting an amine compound having at least two reactive nitrogen moieties with at least one long chain hydrocarbon-substituted reactant in an amount and under conditions sufficient to form a N-containing polymer adduct containing reactive amine groups, and (b) contacting the N-containing polymer adduct with at least one aromatic N-containing monomer under polymerization conditions to graft said N-containing polymer adduct with aromatic N-containing polymer segments. The long chain hydrocarbon-substituted reactant can comprise materials such as (i) long chain hydrocarbons substituted with mono- or dicarboxylic acid, anhydride or ester groups; (ii) halogenated long chain hydrocarbons; (iii) mixtures of formaldehyde and a long chain hydrocarbyl substituted phenol; and (iv) mixtures of formaldehyde and a reaction product formed by reaction of long chain hydrocarbons substituted with mono- or dicarboxylic acid, anhydride or ester groups and an amino-substituted, optionally hydrocarbyl-substituted phenol.

摘要:
The invention concerns amphiphilic graft polymers in which the graft base is a polymer containing at least 5 wt % of units of formula (I) and optionally units of formula (II), R1, R2 being H or C¿1?-C6 alkyl, wherein (a) styrene, C1-C2 alkylstyrene and/or vinyltoluene and optionally (b) other monoethylenically unsaturated monomers which can be copolymerized therewith are grafted onto the graft base in a weight ratio of between 1: 99 and 99: 1, and wherein the group (c) is optionally partially or completely cleaved off the graft polymers, forming amino groups. The invention also concerns processes for preparing and using the amphiphilic graft polymers as consolidating agents for paper, as fixing agents for disruptive water-soluble and water-insoluble agents in paper manufacture, as dispersants for inorganic and organic pigments, dyes, concrete and plant-protecting agents, as detergent additives, as coating material for fertilisers and plant-protecting agents, as floor-maintenance agents, as protective colloids for aqueous polymer dispersions, as thickeners for cosmetic formulations, as conditioners for skin-care agents and as a component of hair-cosmetic preparations and cosmetic preparations for oral hygiene.
