AI Technical Summary

Problems solved by technology

Neutral catalysts are expensive and do not provide control over polyphosphonate block size in block polymers
Additionally, where the neutral catalyst remains in the final polymer product, it can lead to problems such as increased turbidity, reduced hydrolytic stability, reduced optical clarity, darker color and may catalyze thermal degradation of the polymer when used at elevated temperatures

Embodiment 1

[0073] 10 g low molecular weight oligomeric phosphonate (with 1190 g bisphenol A, 18.5 mole percent excess phosphonic acid diester (1595.5 g, methyl diphenoxy-phosphine oxide), 0.6 mole percent low carbon branched compound 1, 1,1-tris(4-hydroxyphenyl)ethane (9.2 g) and sodium phenoxide catalyst (150 mg) dried overnight at 40 °C at 2 mbar were prepared by a melt transesterification process with a T of 90 °C. g and η of 110 rel ) and 30 g of high viscosity polycarbonate (bisphenol A based) (such as Makraolon 3103 from Bayer) and 12 mg of tetraphenylphosphonium phenol transesterification catalyst were combined in a vessel under reduced pressure at 300 °C for 2 hours to remove volatile reactions product. Films of the product cast from dichloromethane solutions after drying were characterized and determined to have a T of 133-134°C g , η of 1.28-1.29 rel and a phosphorus content of approximately 2.72%.

Embodiment 2

[0075] 9.2 g of low molecular weight oligomeric phosphonates (by adding 207.9 g of methyl diphenoxy-phosphine oxide and 177.2 g of bisphenol A, 21.4 g of trisphenol phosphate (trisphenol phosphate) and 0.054 g of phosphonium phenolate catalyst under heating and Under vacuum for 7 hours, 191.4 grams of T with 70°C were generated g and an η of 1.09 rel The product phosphonate oligomers to prepare low M w Phosphonate oligomer) was mixed with 30.8 g of Makrolon 3103 dried under reduced pressure at 80°C overnight and 12 mg of tetraphenylphosphonium phenolate catalyst, and heated at 300°C under vacuum for 2 hours to remove by-products formed. The resulting product was 39.8 g with a T of 140 °C g , η of 1.29 rel ; Infrared (IR) P-O_C peak at 935cm -1 and a poly(phosphonooxycarbonate) with a phosphorus content (measured) of 1.98%.

Embodiment 3

[0077] 10g low molecular weight oligomeric phosphonate (by 75.9 gram methyl diphenoxy-phosphine oxides and 32.2g resorcinol, 0.92g trisphenol phosphate and 24mg phenol tetraphenyl phosphonium catalysts are reacted under heating and reducing The first day under pressure (66.5 g of by-product removed) and the second day of reaction with 24 mg of phosphonium phenolate catalyst under heat and reduced pressure (5.8 g of by-product removed) yielded 35 g of T g and an η of 1.05 rel The low M w Resorcinol phosphonate oligomer) was mixed with 30 g of Makrolon 3103 dried overnight at 80° C. under reduced pressure and 12 mg of phosphonium phenolate catalyst, and heated at 300° C. under vacuum for 4 hours to remove by-products formed. The resulting is a T with a T of 109°C g , η of 1.27 rel , and a phosphorus content (measured) of 4.31% of a slightly yellowish poly(phosphonooxycarbonate).
