Abstract
Disclosed are random copoly(phosphonate carbonate)s with the high molecular weight and narrow molecular weight distribution exhibiting a superior combination of properties compared to prior art.
Claims25
A random copoly(phosphonate carbonate) comprising randomly distributed monomeric units derived from carbonate and phosphonate monomers and having a weight average molecular weight of from about 10,000 g/mole to about 100,000 g/mole as determined by gel permeation chromatography and a polydispersity of from about 2 to about 7.
A polymer blend comprising:
- a random copoly(phosphonate carbonate) comprising randomly distributed monomeric units derived from carbonate and phosphonate monomers and having a phosphorous content of about 2% to about 10% by weight of the total random copoly(phosphonate carbonate) and total acidic components derived from phosphonate monomers of less than about 0.15% by weight;
- and
- at least one other polymer, oligomer, or combination thereof to make a blend or mixture.
A polymer blend comprising:
- a random copoly(phosphonate carbonate) comprising randomly distributed monomeric units derived from carbonate and phosphonate monomers and having a weight average molecular weight of from about 10,000 g/mole to about 100,000 g/mole as determined by gel permeation chromatography and a polydispersity of from about 2 to about 7;
- and
- at least one other polymer, oligomer, or combination thereof to make a blend or mixture.
An article of manufacture comprising a random copoly(phosphonate carbonate) comprising randomly distributed monomeric units derived from carbonate and phosphonate monomers and having a weight average molecular weight of from about 10,000 g/mole to about 100,000 g/mole as determined by gel permeation chromatography and a polydispersity of from about 2 to about 7.
