  • Publication number: 20240101742
    Abstract: A living radical polymer that has a low molecular weight distribution and has a specific functional group at least at one end, and a resin-coated pigment has high dispersibility of a resin composition including the living radical polymer, is excellent in properties such as preservation stability, discharge stability, and color developability in a dispersed state, and is suitably used in a pigment dispersion. A living radical polymer has a specific functional group structure, the living radical polymer includes a polymerization initiator-derived specific organic compound moiety at one end or in a backbone of the living radical polymer and is obtained by reacting a radical generator having a specific functional group with at least any end, for example, an iodine end ascribable to a precursor. A living radical polymer composition includes the same; a resin-coated pigment is obtained by coating with the living radical polymer composition; and a method produces the living radical polymer.

  • Publication number: 20060235135
    Abstract: The present invention relates to a thermoplastic resin crystallization promoter comprising fine carbon fiber consisting of fiber filaments having a diameter of 0.001 ?m to 5 ?m and an aspect ratio of 5 to 15,000, a thermoplastic resin composition consisting of the fine carbon fiber and thermoplastic resin and comprising crystallized resin, and a production method thereof. The crystallization promoter comprising the fine carbon fiber of the present invention enables to crystallize even an amorphous resin, which has an irregular molecular structure and therefore is not crystallized, or which exhibits low crystallization degree and therefore is difficult to crystallize by means of a conventional crystallization promoter. The crystallization promoter provides a thermoplastic resin composition, which, when molded, exhibits improved strength and tribological characteristics and is further reinforced when mixed with a filler.
