| 摘要 |
<p>UV stable linear polyesters, e.g. polyethylene terephthalate, contain in their chain copolymerised 2-hydroxy-di(hydroxyalkoxy)benzophenone. The polyesters are useful for making biaxially oriented films. The polyesters can be made by polycondensation in the presence of 2,4,4'-trihydroxybenzophenone.</p> |
