Poly 4, 4 -diphenylolpropane

The phenomenon has been observed with poly(4,4 -diphenylolpropane isophthalate) [118]... [Pg.390]

The photoyellowing of poly(4,4 -diphenylolpropane isophthalate) (4.58) has been attributed to a photo-Fries rearrangement in a polymer containing o-hydroxybenzophenone as part of the chain structure (4.59) [1391] ... [Pg.294]

Below let us use poly [4-[2-(hydroxyphenyl)propyl-2]-phenyl]phenyl siloxane as an example and illustrate the production of polyphenylsiloxanes from trialkoxyphenylsilane (in our case tributoxy-phenylsilane) synthesised by the second technique, the etherification of phenyltrichlorosilane. The production comprises the following main stages the synthesis of tributoxyphenylsilane and its partial hydrolytic condensation the re-etherification of polybutoxyphenylsiloxane with diphenylolpropane.
