Hydrosilylation of hydride-terminated poly(dimethylsiloxane) with polybutadiene in dilute solution yielded polysiloxane side-loops on a hydrocarbon base, a novel polymer architecture. When the ratio of silane to olefin was increased, the inherent vis

Telomers of perfluoropropylene with alpha,omega- diiodoperfluoroalkanes were converted to branched-chain difunctional condensation monomers. The reaction of ethylene with the telomers gave alpha, omega-bis(iodoethyl)perfluoroalkanes, which were conve

The synthesis of “reactive” ( i.e. aminoacylated) fluoroaliphatic diamines [H2N(CH2)3C(O)NHCH2CH2(CF2)nCH2CH2NHC(O)(CH2)3NH2; n=4,8] has been accomplished through the use of peptide blocking group and coupling techniques. Also, the syntheti

1,2-Difluorodinitroethylene was synthesized by flash vacuum pyrolysis of 1,2-difluorotetranitroethane. X-ray crystallography showed that one of the two nitro groups is out of the plane of the rest of molecule and that the C-C double-bond distance in

The reaction of 1,1-diiododinitroethylene with tetrabutylammonium fluoride gave the tetrabutylammonium salt of 1,1,1-trifluorodinitroethane. Acidification of this salt in ethyl acetate, extraction of tetrabutylammonium salts with water, and addition
