Abstract
Official abstract text for this publication.
A poly(lactic acid) resin composition, including: (a) a poly(lactic acid) resin; and (b) a modifier which is in the form of nanoparticle aggregate with a particle size of less than 1000 nm and uniformly dispersed in the poly(lactic acid) resin, wherein the nanoparticle aggregate is obtained from the polycondensation of at least one metal/nonmetal alkoxide, at least one metal/nonmetal alkoxide having at least one functional group capable of reacting with the poly(lactic acid) resin, or a mixture thereof. A process for preparing a transparent and impact-resistant article from the poly(lactic acid) resin composition of the invention, and articles prepared therefrom are also provided.
First claim
Opening claim text (preview).
We claim: 1. A poly (lactic acid) resin composition, comprising: (a) a poly (lactic acid) resin; and (b) a modifier which is in the form of nanoparticle aggregate with a particle size of less than 1000 nm and uniformly dispersed in the poly(lactic acid) resin, wherein the nanoparticle aggregate is obtained from the polycondensation of at least one metal/nonmetal alkoxide selected from the group consisting of tetramethoxysilane (TMOS) and tetraethoxysilane (TEOS) and at least one…
