Abstract: 1275868 Stretching films CHEMIEFASER LENZING AG 5 May 1970 21683/70 Heading B5B In an apparatus for stretching films of thermoplastic material where conveying rolls, heating, stretching and cooling rolls are used, one or more electrodes are arranged to give an electrostatic charge to the film in contact with the first stretching roll and within a short distance, that is within 7À5 and 10 times the thickness of the non-stretched film, there is a further stretching roll capable of running at a higher speed than the first roll and located within the field of a further electrode. The emission of the electrodes associated with a particular roll impinges upon that part of the film in contact with the surface of the roll in such a fashion that the affected part of the film subtends an angle of at least 30 degrees at the centre of the roll. Two electrodes may be used in association with the first stretching roll so that the combined overlapping fields affect the film in contact with the roll 1 to the extent that this affected part of the film subtends an angle of 180 degrees at the centre of the roll. The stretching rolls have preferably a diameter of between 40 and 120 mm. and their surface is preferably sanded or otherwise roughened. In the embodiment shown in Fig. 3, the film is heated by rolls 4, 5, 6, 7 and 8 and stretched in the gap S 1 between rolls 10 and 10 1 and further stretched in the gap S 2 between rolls 16 and 16 1 . The stretching is preferably such that 80% is carried out between the first pair of rolls. The first roll of each pair is subjected to the influence of electrodes 11 and 11 11 , and 111 and 111 11 , and the second by electrodes 11 and 111 in accordance with the preferred arrangement.

Abstract: 1,180,326. Oxaziridine-cured polysiloxane elastomers. RHONE-POULENC S.A. 21 Aug., 1968 [22 Aug., 1967], No. 40034/68. Heading C3T. An elastomer-forming composition comprises an essentially linear organopolysiloxane containing at least one alkenyl group per molecule and an oxaziridine. Suitable oxaziridines have the formula wherein R 1 and R 2 are each H or a C 1-4 alkyl group or together form an alkylene chain and R 3 is a C 1-4 alkyl or cycloalkyl or phenyl group. They are used in amounts providing 2-3 molecules of oxaziridine per olefinic double bond in the polysiloxane. The polysiloxane preferably has a viscosity of 500 to 30,000,000 cP at 25‹ C. and one double bond per 100 to 1500 silicon atoms. The composition may also contain activators, e.g. iron or manganese octoates; fillers, e.g. fume silicas, silica aerogels, optionally treated with an organosilicon compound, ground silica or quartz, Al 2 O 3 , TiO 2 , CaCO 3 , C black, graphite, P.V.C. and cork powder; pigments; and anti-structure additives, e.g. dimethyl (tetramethylethylenedioxy) silane and short chain hydroxy-terminated polysiloxanes. In examples a polysiloxane is mixed with fume silica treated with octamethylcyclotetrasiloxane and dimethyl (tetramethylethylenedioxy) silane, iron and manganese octoates and methylethyl-N-isopropyl-, isopropyl-N-tbutyl-, isopropyl-N-isopropyl-, dimethyl-N- isopropyl., methylethyl-N-eyclohexyl- and 3 : 3-pentamethylene-oxaziridine. The polysiloxanes used are dimethylpolysiloxanes containing one methylvinylsolixane group per 500 or 700 Si atoms and optionally some diphenylsiloxane groups (Example 2).

Abstract: An organopolysiloxane of the formula wherein R1, R2 and R3 are each a saturated or unsaturated hydrocarbon (h.c.) radical, a sat. or unsat. cycloaliphatic h.c. radical, an aryl radical or an inertly substituted aforesaid radical, and n is a positive integer, can be made by reacting where X is a hydrolysable atom or radical, with The reaction, which occurs spontaneously on mixing of the reactants, may be effected with or without a diluent at temperatures, e.g. from -50 DEG to 100 DEG C. Examples describe the above preparation of (1) 1,5-dimethyl-1,1,5,5-tetrahydrogeno - 3,3 - diphenyltrisiloxane; (2) 1,1,7,7 - tetrahydro - 1,3,3,5,5,7 - hexamethyl tetrasiloxane; (3, 4, 5) CH3SiH2-[OSi(CH3)2-]nH2Si CH3, wherein n is 8, 140 and 335 respectively; (6) 1,7 - dimethyl - 1,1,7,7 - tetrahydro - 3,3,5,5 - tetraphenyltetrasiloxane; (7) CH3SiH2-[OSi(CH3)(C6H5)]180 -OH2SiCH3; and (8) C4H9-SiH2-[OSi(CH3)2]120 -OH2SiCH3.
