More Information
Summary:A process is provided for preparing polyester composite materials, comprising polymerizing at least one polyester precursor in the presence of filler microparticles and/or nanoparticles and organosilane having nucleophilic functionality. The organosilane is added as a distinct ingredient. The polyester composites so prepared have low acid end group content, thus improved hydrolytic and melt stability and improved elongation at break.
