Abstract [en]

Branched aliphatic polycarbonates were synthesized by ring opening polymerization of 5,5-dimethyl-1,2-dioxane-2-one (NPC) initiated from polyfunctional alcohols and a commercial hyperbranched polyester (BOLTORN(R)). Polymerizations in the presence of fumaric acid under bulk conditions allowed high conversion (80%) without gelation. The synthesis of polymers with long chain branches was confirmed by size exclusion chromatography and universal calibration. The Mark-Houwink exponent decreased, indicating an increased density, while increasing the number of arms. The star polymers with up to four arms showed thermal properties T-g (20-30degreesC) and T-m (100-110degreesC) similar to linear PNPC.
