摘要:
A novel monomer design for the synthesis of PPE-type polymers containing conjugated segments of well-defined length connected by flexible linkers under Sonogashira reaction conditions is presented. The resulting polymers retain the photophysical properties of a fully conjugated PPE. The extent of incorporation of the flexible units along the backbone is governed by the comonomer feed ratio and can be varied in a statistically predictable fashion.

A composition of (a) of product of condensing a phenylene di- or tri(methyl halide) or di- or tri-(methyl alkoxy ether) with a molar excess of a phenol and (b) 10-20% of hexamethylene tetramine is curable and can be used in the preparation of moulding compounds, laminates and coating compositions.
摘要:
The compounds are of the class of dithiobis(betaarylalkylene)diphenols and chain-extended polydithiopolyphenols derived thereform. They are useful as anti-oxidants in compositions containing unsaturated rubber - that is, so-called diene rubbers. A typical compound of the class is 4,4''dithiobis(beta-phenylethylene)diphenol, made by the condensation of one mole of bis(beta-chlorophenethyl)disulfide with two moles of phenol. Chain extension is apt to occur by reaction of the first-formed dithio-diphenol with additional amounts of the dichloro coupling agent and the starting phenol, forming poly(dithio) polyphenolic compounds having repeated alternating units of the coupler and phenol moieties.
