ABSTRACT:
This invention relates to a core-shell polymer which is useful for polyoxymethylene resin, a polyoxymethylene resin composition containing the core-shell polymer and a molded article made of the polyoxymethylene resin composition.
The core-shell polymer comprises a rubbery polymer core and a glassy polymer shell and has substantially no detectable anion.
This core-shell polymer makes the molded articles be improved on the impact strength, elongation at the weld line, etc. The molded articles is used as various products (such as gears, reels, etc.).
