Abstract
Interpenetrating polymer network composition, of shaped solid polyester material, e.g. new or reused polyester containing particles, sheeting, fiber or fiber fabric, in a matrix of curable prepolymer resin, e.g. a thermosetting phenol-aldehyde resin of basic pH for providing a flame retardant composition, an interfacial dissolving agent for the polyester material, e.g. an aromatic alcohol and/or a halohydrocarbon, optionally an accelerator for the resin, e.g. a weak acid, and optionally a filler, e.g. in a weight ratio of matrix to polyester material of about 0.25-15:1, wherein the polyester material is distributed, e.g. dissolved, in the manner of a filler in random directional spatial orientation in the matrix and/or preferably is polyester containing linear fiber or fiber fabric arranged as structually reinforcing material in definite directional spatial orientation in the matrix, the composition being consolidated and heat cured to form a prepreg product, and then hot compression molded to form a finally cured, especially flame retardant, structural product.
