摘要:
The invention provides a production process of a flame-retardant polyester copolymer, having a first step of adding a catalyst to a 2,5-furan dicarboxylic acid compound, an aliphatic or alicyclic diol, itaconic acid and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide to obtain an oligomer, and a second step of adding a catalyst to the oligomer obtained in the first step to conduct polycondensation, thereby obtaining the flame-retardant polyester copolymer.

摘要:
There is provided a novel nonflammable release agent composition for a plastic mold containing: (a) a hydrofluoroether; (b) fluorine oil; and (c) a fluorine-based surfactant, in which the content of the ingredient (a) is 50 wt % or more. The composition is lowly toxic, noncombustible, and more chemically stable than a conventional one, and brings together high persistence of releasability and sufficient durability.
摘要:
There is provided a multilayer molding method using an unused thermoplastic resin material and a recycled thermoplastic resin material, including molding at least one layer through an injection compression molding method. The multilayer molding method allows improvement in use rate of the recycled thermoplastic resin material with favorable appearance and sufficient mechanical strength maintained in reuse of the recycled thermoplastic resin into a product.
