Title:
POLYMER COMPOSITION HAVING GOOD SUPERIOR THERMAL CONDUCTIVITY, AND A METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2012/157841
Kind Code:
A1
Abstract:
The present invention relates to a polymer composition having good superior thermal conductivity, to a mold manufactured from the polymer composition, and to a method for manufacturing the composition and the mold. ParticularlyMore particularly, the present invention relates to a polymer composition comprising: 10 to 80 volume % of a polycarbonate-based resin; 10 to 80 volume % of a polyolefin-based resin; and 5 to 80 volume % of a thermo thermo-conductive filler, and a mold manufactured from the polymer composition. Also provided is a method for preparing the polymer composition, comprising the steps of: mixing 10 to 80 volume % of a polycarbonate-based resin, 10 to 80 volume % of a polyolefin-based resin, and 5 to 80 volume % of a thermo thermo-conductive filler; and extruding the thus-obtained mixture. According to the present invention, the thermal conductivity of the polymer composition can be largely significantly increased by effectively forming a network between fillers through controlling the morphology of the polymers in the composition even by when using only one kind of filler. The mold manufactured by using the polymer composition of the present invention can be usefully applied as a partin products such as a heat sink for electronic instruments.
