The present invention relates to a method of preparing a thermoplastic resin. More particularly, the present invention relates to a method of preparing a thermoplastic resin, the method including A) a step of coagulating an emulsion-polymerized latex with an acid; B) a step of treating the coagulated aggregate (slurry) with a base, followed by dehydration; and C) a step of treating the dehydrated wet powder with an acid, followed by dehydration. A method of preparing a thermoplastic resin which exhibits reduced gas generation, color improvement, and superior thermal stability is provided.

An implant includes a section made of polymer, wherein at least a portion of the section has a layer of a polymerizable and/or cross-linkable material. A method for fixation of a bone plate having several plate holes using the implant includes removing a cover sheet protecting the layer of polymerizable and/or cross-linkable material, activating the layer of polymerizable and/or cross-linkable material with electromagnetic energy or with moisture, introducing the implant into one of the plate holes of the bone plate when the bone plate is positioned on a bone, pressing on an end of the implant in order to contact the activated layer of polymerizable and/or cross-linkable material with the bone underneath the bone plate, and allowing the activated and pressurized layer of polymerizable and/or cross-linkable material to polymerize and/or cross-link and to adhere to the bone.

A method for manufacturing a patterned polyimide aerogel film on a substrate includes: dispensing a polyimide prepolymer sol onto a first portion of a surface of a substrate, a second portion of the surface of the substrate being substantially free of the polyimide prepolymer sol; forming a patterned film of a polyimide prepolymer gel on the substrate from the polyimide prepolymer sol; drying the polyimide prepolymer gel to form a patterned film of a polyimide prepolymer aerogel on the substrate; and curing the polyimide prepolymer aerogel on the substrate to form the patterned polyimide aerogel film on the first portion of the surface of the substrate, the second portion of the surface of the substrate being substantially free of the patterned polyimide aerogel film.
