A vinyl chloride homopolymer or copolymer composition contains a silane, a compound capable of generating free radicals and a stabilizer comprising a lead compound or an organotin compound which is effective to prevent discoloration and degradation of the homopolymer or copolymer and does not inhibit the grafting of the vinyl silane on the homopolymer or copolymer. The graft homopolymer or copolymer is exposed to moisture to cross-link it, suitably after molding or otherwise fabricating the graft polymer to form an article. There is also provided a method of moisture cross-linking poly(vinyl chloride) and vinyl chloride copolymers.

The invention relates to a method for the high yield production of dicarboxylic acids such as azelaic acid by the controlled two step oxidation of an unsaturated hydrocarbon substrate. The method consists of two steps and involves the derivatization of the unsaturated substrate which locks and directs oxidative cleavage at the site of unsaturation to yield the desired acids.

The invention is concerned with a novel polymer addition product comprising hydrophilic polymer backbone having a molecular weight of at least about 5,000 and to which are attached amino acid containing pendants, the pendants containing at least one arginine or lysine amino acid. The polymeric compounds of the invention are highly efficient adsorbents for bilirubin and other bile pigments, as well as for bile acids such as cholic acid.
