    摘要: A device for polymerizing lactams in molds includes a hopper for storing solid lactam and a lactam feeding component that includes a plasticizing screw so as the lactam to be melted and simultaneously taken in a dosed manner to a mixing chamber. The device further includes a first dosing component to feed a liquid initiator, and a second dosing component to feed a liquid activator. The mixing chamber is configured to receive in a dosed manner the lactam, the initiator, and the activator from the feeding and dosing components. The mixing chamber has three separate inlets to receive, separately, the lactam, the initiator, and the activator, to allow them to flow into the mixing chamber coming into contact with one another for the first time, at the moment immediately prior to entering into a mold located adjacent the chamber and arranged for the polymerization reaction to take place inside the mold.

    摘要: Disclosed are a method for preparing biodegradable polymer materials, biodegradable polymer materials, and a product for fixing bone. The method includes a complex preparing step of preparing polylactide stereoisomeric complex by using a polymer having weight-average molecular weight more than 100,000 g/mol; a molding step of compression-molding the complex; a cooling step of cooling the compression-molded complex; and an extruding step of solid state extruding the cooled complex. Biodegradable polymer materials prepared by the method may be applied to a product for fixing bone or spine requiring high strength. Biodegradable polymer materials may have no corrosion in the body, may require no additional operation for removal after healing bones and tissues, and may prevent stress shielding.
