    Abstract: PURPOSE:To manufacture the crosslinked form with a good appearance under a good productivity by a method wherein thermplastic polyester resin powder is mixed with crosslinking agent and is pressurized to form and crosslink it simultaneously under heating to a specified temperature. CONSTITUTION:The thermoplastic polyester resin powder having particle diameters of 2,000mu or less is mixed with 0.1-10wt% of crosslinking agent. Subsequently, this mixture is pressurized and formed under heating to a temperature higher than the melting or softening point and lower than the decomposition temperature of the thermoplastic polyester resin to react the crosslinking agent and the thermoplastic polyester resin simultaneously with this forming. Polyethylene terephthalate and polybutylene terephthalate, both having good mechanical properties, are preferable t o be utilized as the thermoplastic polyester. Polyisocyanate is especially preferable to be utilized as the crossliking agent.

    Abstract: PURPOSE:To obtain a molded product made of thermoplastic polyamide resin and crosslinked in a simple manner, by a method wherein polyamide resin powder of 10 meshes and below and a crosslinking agent are mixed, and when said mixture is formed by pressure at a given temperature, they, simultaneously, are reacted to each other. CONSTITUTION:Thermoplastic resin having particle diameter of below 10 meshes and a crosslinking agent are mixed, and said mixture is formed by pressure as it is heated at higher than a melting point or softening point of thermoplastic polyamide resin and at below a decomposition temperature. Simultaneously, the crosslinking agent and polyamide resin are reacted to each other to produce a crosslinked molded product. Aliphatic polyamide such as nylon 6, nylon 66, nylon 610, etc. can be used as the thermoplastic polyamide resin, and polyisocianate, ethylene oxide, etc., can be used as the crosslinking agent. Multifunctional epoxide is especially suitable for said crosslinking agent.
