Title: Chlorinated polyethylene elastomers
IPC: C08F8/00
Filed: 1964-12-21
Abstract: Chlorinated polyethylene containing carboxylic ester groups in which the alcohol residue is aliphatic and ethylenically unsaturated and contains 3 to 20 carbon atoms, the proportion of chlorine atoms being sufficient to render the polymer elastomeric and the proportion of ester groups being sufficient to render it sulphurcurable may be prepared by chlorocarboxylating with oxalyl chloride or phosgene a solution of polyethylene and then adding, preferably in excess, the unsaturated alcohol.  In the chlorocarboxylating the solvent employed for the polyethylene should be substantially inert to chlorine, free radical catalysts may be used and suitable temperatures are 100 DEG to 200 DEG  C.  After esterification with the unsaturated alcohol, the esterified carboxylated polyethylene can be isolated by precipitation from solution.  Alcohols mentioned are allyl, oleyl, crotyl, o -undecylenyl and 9-eicosenyl alcohols and 1-butene 3-ol; 3-hexene-1-ol; 1-heptene-4-ol and 2-methyl-2-heptene-6-ol.  The esterified carboxylated chlorinated polyethylene may be cured with organic peroxides or sulphur.  In the examples:  (1) linear polyethylene dissolved in 1,2,4-trichlorobenzene is treated with oxalyl chloride and benzoyl peroxide.  After adding 1,11 - azobisisobutyronitrile, chlorine is added until the chlorine content has reached 31%. The mixture is then treated with allyl alcohol to produce the chlorinated polyethylene of the invention and (2) a solution of chlorocarboxylated polyethylene prepared as in Example 1 except that it contains 35.9% of chlorine, is treated with oleyl alcohol.

In Fig. 4, which shows the generator just prior to actuation, the movable elements 2a, 2b have been forced apart by applying pressurized fluid above piston 172 to move it, and hence pushmember 177, downwards, after which the pushmember has been locked in position by the frictional grip of a flexible wall 179 of a fluidpressurized chamber 180 while piston 172 has been returned to its upper position by fluid pressure in chamber 185 of a piston and cylinder assembly 173, 174. To actuate the source, the pressure in chamber 180 is reduced to unlock elements 2a, 2b which then impact each other under ambient hydrostatic forces. The piston and cylinder assembly 173, 174 is disposed above piston 172, and outside cylinder 170, in a second embodiment Fig. 5, (not shown). In the Fig. 8 embodiment, push-member 217 for moving the elements 2a, 2b apart is locked in its lower-most position by hydraulic pressure acting above a flange 218 which seats against a valve seating 213. To actuate the generator, fluid pressure is applied below the flange, via conduit 216 to unseat the flange, whereupon elements 2a, 2b accelerate under ambient hydrostatic forces and impact each other.
