IMPROVED WEATHER RESISTANT RESIN COMPOSITION COMPRISING POLYSULFONE/AROMATIC COPOLYESTER BLEND |
摘要 |
A composition with improved weatherability consisting essentially of about 1 wt.% to about 99 wt.% of a polysulfone and about 1 wt.% to about 99 wt.% of a polyarylate copolyester. The polyester is formed by reacting about 20 mole % to about 30 mole % terephthalic acid, about 20 mole % to about 30 mole % isophthalic acid, and about 40 mole % to about 60 mole bisphenol-A. The polysulfone mixed with said polyester has better impact strength retention than does polysulfone alone. |
