| Abstract: | Using the molten polycondensation,the second to fourth generation of hyperbranched polyesters with a great number of hydroxyl groups were synthesized and characterized based on the pentaerythritol as core and 2,2-bis(hydroxymethyl) propionic acid as arm.They had high branched degrees,low viscosity and good thermal stability.By methacryloyl anhydride,the hyperbranched polyesters were modified to be the hyperbranched methacrylates with C=C at the chain ends.The percent conversion could be reached above 89% un... |
