    摘要: The present invention addresses the problem of providing a fluorine-containing aromatic polymer; a method for producing the fluorine-containing aromatic polymer; etc. The problem can be solved by: a polymer having a monomer unit represented by formula (1) (wherein R1 in each occurrence is independently a halogen atom, NR11R12 (wherein R11 and R12 are independently a hydrogen atom or an organic group), or an organic group; n1 is an integer of 0 to 4; two R1s that can be present in the ortho-positions may form a ring together with two carbon atoms on the adjacent benzene ring, wherein the formed ring may have an organic group as a substituent; and L1 is a single bond, an oxygen atom, a sulfur atom, -L11-O—, —O-L12-O—, -L13-S—, or —S-L14-S— (wherein L11 to L14 are each independently an alkylene group optionally having one or more substituents); etc.

    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.
