Aromatic polyformal-polycarbonate block polymers and method for making same |
| abstract |
There are provided aromatic polyformal-polycarbonate block polymers and method for making such materials. The polyformal-polycarbonate block polymers can be made by phosgenating a mixture of a bisphenol and oligomeric aromatic polyformal having terminal phenolic groups. The aromatic block polymers are high performance thermoplastics having improved hydrolytic stability compared to aromatic polycarbonates and improved heat distortion temperature compared to conventional aromatic polyformal. |
