摘要： A process for producing polyalkenyl acylating agent, wherein, upon completion of the thermal reaction of a polyalkene and an unsaturated mono- or dicarboxylic acid or anhydride compound, the reaction mixture is allowed to cool to below the reaction temperature, an additional amount of unsaturated mono- or dicarboxylic acid or anhydride compound is added to the cooled reaction mixture, which is then maintained in the reactor for a time period, optionally with agitation. Reducing the temperature of the reaction mixture prior to the introduction of additional unsaturated mono- or dicarboxylic acid or anhydride compound minimizes further reaction between the additional unsaturated mono- or dicarboxylic acid or anhydride compound and any remaining unreacted polyalkene, as well as self-polymerization of the unsaturated mono- or dicarboxylic acid or anhydride compound. Polymerized unsaturated mono- or dicarboxylic acid or anhydride compound in the reactor, suspended in the reaction mixture in the form of sediment or deposited on the internal walls of the reactor vessel as tar, is dissolved by the additional unsaturated mono- or dicarboxylic acid or anhydride compound and removed from the reactor upon draining of the reactor vessel.

摘要： A curable thermosetting prepolymerized imide resin composition is prepared by chemically reacting, at a temperature below 150.degree. C., a liquid mixture of a carboxy-terminated polybutadiene/acrylonitrile (CTBN) and a co-reactant containing at least one N,N'-bisimide of an unsaturated carboxylic acid of general formula (I) ##STR1## where B represents a divalent radical containing a carbon-carbon double bond and A represents a divalent radical having at least two carbon atoms, at least one monoimide, and at least one organic hydrazide, to yield a curable thermosetting prepolymerized imide resin composition containing copolymerized CTBN and co-reactant. A resin composition prepared by this method may be cured at a temperature between 100.degree. C. and 350.degree. C. to yield a fully cross-linked polymimide matrix containing a dispersion of phase-separated solid particles of copolymerized CTBN and co-reagent, said matrix having a lap shear strength at 20.degree. C. at least 50% greater than that of a fully cross-linked polyimide cured from the co-reactant alone.
