摘要: A coated particulate filler to the surface of which there is bound an acid group-containing organic polymer which also comprises a nitrogen-containing group capable of reacting with an organic polymeric material. The acidic group may be a carboxylic acid group and the nitrogen-containing group may be an amide group or an amine group, especially a alkylamine or a polyakylamine derivative of an amine group. The organic polymeric material may contain ethylenically unsaturated groups or halogen groups, and reaction may take place during cross-linking of the organic polymeric material. Compositions comprising coated particulate filler and organic polymeric material have improved tensile modulus.
