  • Preparation of interpenetrating polymer network composition
    Patent number: 5162414
    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.
