摘要： An object of the present invention is to provide a method for producing a polymeric molded product, which does not undergo a considerable molecular weight reduction during melt-molding, even in a polymer may easily lose its molecular weight when it is in a melted state. The present invention provides a method for producing a polymeric molded product, which comprises melt-molding a polymer comprising lamellar crystals that are different in lamella thickness, in a temperature range where some of the lamellar crystals undergo melting and flowing, and the other balance lamellar crystals remain unmelted.

摘要： An object of the present invention is to provide a method for producing a polymeric molded product, the method enabling expansion of a temperature range that can be used for partial melting. The present invention provides a method for producing a polymeric molded product, which comprises subjecting a crystalline polyhydroxyalkanoate to a heating treatment at a temperature equal to or higher than a glass transition temperature; and melt-molding a polyhydroxyalkanoate yielded by the heating treatment, which comprises lamellar crystals that are different in lamellar thickness, in a temperature range where some of the lamellar crystals undergo melting and flowing, and the other balance lamellar crystals remain unmelted.

摘要： A method for forming a preform for a thermoplastic retention device is provided. The method includes providing a thermoplastic base material and blending the base material with one or more chemical agents to form a polymer blend. The chemical agents are configured to modify a polymer chain of the base material when the polymer blend is exposed to radiation. The method further includes forming the polymer blend into a filament sized for a three-dimensional printing platform and printing a preform shape from the filament using the three-dimensional printing platform. After the printed preform is hardened, the method includes exposing the printed preform shape to radiation sufficient to cause a reaction between the one or more chemical agents and the base material.

摘要： Methods of making fiber reinforced composite articles are described. The methods may include the step of providing a pre-impregnated fiber-containing thermoplastic material to a mold for the article. The pre-impregnated fiber-containing thermoplastic material may include: (i) a plurality of fibers, and (ii) a first thermoplastic polymer made from a first reactive thermoplastic resin. Reactants of a second reactive thermoplastic resin may be introduced to fill open spaces in the mold that are left by the pre-impregnated fiber-containing thermoplastic material. The second reactive thermoplastic resin may then be polymerized to form a second thermoplastic polymer. The final fiber reinforced composite article includes at least two spatially distinct regions of thermoplastic polymer.
