  • Patent number: 4451646
    Abstract: Amorphous, highly viscous high molecular weight copolyethers containing in excess of 200 total repeating units and formed of --CF.sub.2 --CF.sub.2 --O-- and --CF.sub.2 --O-- repeating units randomly distributed along the chain and linked to each other either directly or through an oxygen atom, in which latter case a peroxy group is present along the chain. These copolyethers, which are useful for preparing bifunctional telomers, high molecular weight fluoropolymers, and highly stable lubricants and heat exchange materials, are prepared by reacting molecular oxygen with tetrafluoroethylene dissolved in a fluorinated or chlorofluorinated solvent selected from the group consisting of dichlorodifluoromethane, perfluorocyclobutane, perfluorodimethylcyclobutane, 1,2-dichloro-hexafluoropropane and 1,2-dichloro-tetrafluoroethane in the presence of ultraviolet radiation and under such conditions that the molar ratio of the tetrafluoroethylene to the oxygen in the reactant feed is between about 0.

  • Patent number: 4440876
    Abstract: A process for obtaining fiber-reinforced foams suitable to be transformed to reinforced solid cellular materials having a density lower than 0.7 kg/l, if inert fillers are not present, and lower than 1 kg/l if inert fillers are present as well, essentially by mechanical incorporation of gas or a mixture of gases into an unsaturated polyester resin containing conventional additives is described. As reinforcing materials synthetic, vegetable or mineral fibers having a maximum length of 3 mm are employed. The mixture of the resin with the fibers, and optionally with the inert fillers, is conveyed by at least one pump to a mechanical foaming device which introduces into the mixture gas in form of small bubbles, homogeneously and uniformly distributed therein.
