Abstract: Composite fibers (I) are prepared by heating a mixture of a PTFE or PTFE-copolymer-dispersion or powder with a fine particulate inorganic material and a fiber forming material with stirring such that the PTFE or PTFE copolymer becomes capable of flow but does not decompose and the dispersing agent is removed (in the case of a dispersion) and shearing the mixture in a mixer having a Froude number of more than 1. An Independent claim is included for a process for the production of a diaphragm by addition of (I) to a solution containing water and a thickening agent; filtering of the mixture with suction over a porous support to layer the composite fiber (I); drying of the coated porous support and heating at 90-390 degrees C.

Abstract: The use of copolymers (CP) as adhesives is new. These copolymers (CP) are derived from (a) 70-100 wt.% vinyl ethers, and (b) 0-30 wt.% other comonomers, and contain hydrolysable organosilicon groups of formula -Si(R )x(OR )3-x (I), in which R , R = 1-20C alkyl or 5-30C aryl, alkaryl or aralkyl; and x = 0, 1 or 2. Also claimed are (i) adhesives containing copolymers (CP), and (ii) copolymers (CP) as above, in which the hydrolysable groups (I) are obtained by copolymerisation with vinyl ethers of formula H2C=CH-O-Z-O-CH2CH2-SiR x(OR )3-x (III), in which R , R , x = as above; and Z = 1-20C hydrocarbyl or halohydrocarbyl, optionally containing more oxygen atoms.
