POLYSILOXANE-MODIFIED POLYLACTIC ACID COMPOSITION, COMPOSITION UTILIZING SAME, MOLDED ARTICLE, AND PRODUCTION METHOD

WIPO Patent Application WO/2010/101291

A1

Disclosed are a polysiloxane-modified polylactic acid resin, composition using same, molded article, and production method, whereby it is possible to produce a molded article via a simple method, and where said article may be used in applications demanding a high level of shock resistance as an alternative to ABS resin or the like, has a similar level of shock resistance as said substances, has superior flexibility with respect to rupture bending strain and tensile breaking strain, and has bleed resistance. The polysiloxane-modified polylactic acid resin has a segment which is a polylactic acid compound, and a segment which is an amino polysiloxane compound which has an amine group. With respect to the amino polysiloxane compound, amine groups are on average contained in the range of 0.01 to 2.5% inclusive by mass, and with respect to the polylactic acid compound, are on average contained in the range of 3 to 300 ppm inclusive by mass.
