<p><P>PROBLEM TO BE SOLVED: To develop a resin composition which does not deteriorate original moldability and stiffness inherent in a styrene-based resin by formulating a resin derived from a plant to the styrene-based resin, and to put it to practical use as a material for a foam, a sheet and an enclosure, etc. in order to reduce petroleum usage and maintain the environment. <P>SOLUTION: This resin composition comprises a styrene-based resin (A) of 87-15 wt.%, a hydrogenated block copolymer (B) of 5-30 wt.% containing a conjugated diene and a vinyl aromatic hydrocarbon, a block copolymer (C) of 3-20 wt.% containing a styrene-based monomer and a (meth)acrylate monomer, and polylactic acid (D) of 5-50 wt.%. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
