Document Type and Number:
WIPO Patent Application WO/2012/014676
Kind Code:
A1
Abstract:
Provided are a fiber-reinforced thermoplastic resin composition excellent in terms of dispersion property, moldability, rigidity, and reinforcing property and a process for producing the resin composition. This fiber-reinforced thermoplastic resin composition comprises (a) 100 parts by weight of a polyolefin (5), (b) 10-600 parts by weight of a rubbery polymer (7) having a glass transition temperature of 0ºC or lower, (c) 10-500 parts by weight of spherical silica (3) having an average particle diameter of 1 µm or less and a water content of 1,000 ppm or less, (d) 1-400 parts by weight of ultrafine fibers of a thermoplastic polymer (1) having amide groups in the main chain, and (e) 0.1-20 parts by weight of a silane coupling agent, wherein the ingredient (d) has been dispersed as ultrafine fibers having an average diameter of 1 µm or less in a matrix comprising the ingredients (a), (b), and (c), and the ingredients (a), (b), (c), and (d) have been chemically bonded through the ingredient (e).
