POLYCARBONATE-POLY(ETHER-ESTER) COPOLYMER COMPOSITION, METHOD OF MANUFACTURE, AND ARTICLES THEREFROM |
摘要 |
<p>A composition comprising: a polycarbonate comprising units derived from a bisphenol cyclohexylidene of the formula: wherein Rc1 and Rd1 are each independently C1-12 alkyl, Rc2 and Rd2 are each independently hydrogen or C1-12 alkyl, Rg is C1-12 alkyl or halogen, and t is 0 to 10; and a poly(ether-ester) copolymer comprising 40 to 60 wt% of polyester hard block units derived from a C6-C24 aromatic dicarboxylic acid or a C6-C24 alicyclic dicarboxylic acid and at least one glycol component, wherein when the C6-C24 aromatic dicarboxylic acid comprises terephthalic acid, isophthalic acid groups are present in an amount from 0 to 30 mole%, based on the total moles of isophthalic acid groups and terephthalic acid groups in the hard block units, and 40 to 60 wt% of polyether soft block units derived from poly(oxytetramethylene) glycol, wherein the molecular weight of the poly(oxytetramethylene) glycol groups is 300 to 1800 Daltons.</p> |
