  • Patent number: 5811036
    Abstract: A process for recycling a thermoplastic resin covered with a thermosetting-resin paint film includes the steps of decomposing the paint film by bringing the thermoplastic resin covered with the paint film into contact with a paint-film-decomposing agent in a molten state, and removing decomposed products, resulting from the paint film and the paint-film-decomposing agent, and the residual paint-film-decomposing agent by degassification to prepare a recycled resin. The paint-film-decomposing agent can be primary amines and/or secondary amines having a boiling point of 250.degree. C. or less, or being decomposed at 250.degree. C. or less, or can be tertiary amines and/or quaternary amines having a boiling point of 250.degree. C. or less, or being decomposed at 250.degree. C. or less to which water and/or alcohols is added.

  • Patent number: 4889885
    Abstract: A composite material comprising a resin other than polyamide resin and a layered silicate dispersed therein, said layered silicate having a layer thickness of 7 to 12 .ANG. and an interlayer distance of 30 .ANG. or above. Owing to the layered silicate uniformly dispersed in the resin matrix, the composite material is superior in mechanical characteristics and heat resistance. It also has good water resistance and chemical resistance.
