摘要： The cross-linking or curing of thermosetting resins and of hot curable elastomers is carried out by heating the material or the article comprising the resin (or the elastomer) by saturated vapor of the commercial perfluoropolyether having an average boiling point corresponding to the temperature necessary for the cross-linking and having a point range not exceeding 12.degree. C. (measured according to ASTM D 1078) in the presence of a chlorofluorohydrocarbon secondary vapor.

摘要： Non-fluorinated tertiary aminic compounds, comprising two or more functional groups containing at least three active H, of the hydroxyl or aminic or thiol type, are utilized, in the form of a homogeneous mixture with perfluoropolyethers having hydroxy end groups, to prepare by means of polycondensation and cross-linking reaction with fluorinated or non-fluorinated polyisocyanates, carried out in the absence of catalysts, the corresponding polymers containing the perfluoropolyethereal chain deriving from the perfluoropolyether having hydroxy end groups.

摘要： Non-fluorinated epoxy resins of a known type are cross-linked by means of polyfunctional fluoroalkanes containing groups which are reactive with the epoxy groups and/or with the hydroxy groups present in the starting resin. The cross-linked products so obtained, having a fluorine content not higher than 15% by weight, and preferably ranging from 1% to 5%, exhibit a complex of properties which are typical of the corresponding fluorinated resins having a much higher fluorine content; in particular, oil- and water-repellency, resistance to hydrolysis and to solvents, and minimum absorption of water.

摘要： Fluorinated polyurethanes containing blocks having a perfluoropolyethereal structure, with rubber-like properties, alternated with stiff structural units are taught. The stiff units are at least partially provided with a double bond of the olefinic type, which is suitable for causing the cross-linking of the polymeric chains with a cross-linking system of the radicalic type.

摘要： The invention relates to polyurethanes comprising polyoxyperfluoroalkylene blocks of rubber-like nature and rigid segments derived from short-chain aliphatic diols, optionally from aliphatic diamines, and from aliphatic or cycloaliphatic or aromatic diisocyanate. The number of the rigid-type segments is equal to or greater than the number of the polyoxyperfluoroalkylene blocks. The polyurethane are characterized by a glass transition temperature lower than -80.degree. C., a tensile strength greater than 30 kg/cm.sup.2, a hardness between 50 Shore A and 75 Shore D, and good thermoforming characteristics.
