摘要： Disclosed herein is a method for producing a 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine. The method comprises forming a reaction mixture comprising at least one substituted or unsubstituted phenolphthalein compound, at least one substituted or unsubstituted primary hydrocarbyl amine, and an acid catalyst; and heating the reaction mixture to form 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine. An adduct of the 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine is formed either by using an excess of the primary hydrocarbyl amine in the first heating step, or by isolating crude 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine after the heating step and then reacting with a further amount of the primary hydrocarbyl amine. The 2-hydrocarbyl-3,3-bis(4-hydroxyaryl)phthalimidine has a formula: where R1 is selected from the group consisting of a hydrogen and a hydrocarbyl group, and R2 is selected from the group consisting of a hydrogen, a hydrocarbyl group, and a halogen.

摘要： A thermoplastic resin composition with improved flame retardance, flow and heat deflection temperature includes a thermoplastic resin; resorcinol diphenyl phosphate; and an additive blend. The additive blend includes a combination of melamine polyphosphate and ferrocene. The thermoplastic composition reduces the amounts of resorcinol diphenyl phosphate required for effective flame retardancy. Moreover, the effective amounts of melamine polyphosphate and ferrocene do not deleteriously affect other properties of the thermoplastic composition such as Izod strength, flow properties, and heat deflection temperatures. A process for manufacturing a thermoplastic composition is also disclosed.
