Title: Copolymers of asymmetrical dichloroethylene with polymerisable unsaturated ketones
IPC: C08F16/36
Filed: 1943-10-04
Abstract: Asymmetrical dichloroethylene and a ketone of the formula <FORM:0572946/IV/1> , wherein R is hydrogen, an alkyl group containing 1 to 6 carbon atoms, an aryl group or halogen and R1 is a monovalent hydrocarbon group are copolymerized in such proportions that the copolymer contains 40 to 95 per cent of asymmetrical dichloroethylene.  Ketones specified are methyl, ethyl, propyl, isopropyl, butyl, hexyl, octyl, phenyl, p-tolyl, benzyl and cyclohexyl vinyl ketones, isopropenyl methyl ketone, 2-chloro-1-butene-3-one, 2-methyl-1-buten-3-one and 2-phenyl-1-buten-3-one.  Preferably, a mixture of the monomers is emulsified in an acidic aqueous medium containing an emulsifying agent and a catalyst and heated at 40-60 DEG  C.  The process may be carried out continuously in an inclined heated tube.  The emulsion is steam distilled to remove residual monomer, diluted and precipitated by an electrolyte such as hydrochloric, sulphuric or phosphoric acids, aluminium sulphate, calcium chloride or sodium chloride.  The precipitate is washed with water and then with alcohol or an alcohol - aromatic hydrocarbon mixture. Suitable dispersing agents are alkyl naphthalene sulphonic acids, alkyl sulphonic acids and salts of acid sulphuric esters of alcohols containing 12 to 18 carbon atoms, e.g. the sodium salt of a  - acetoxyoctadecyl - sulphuric acid.  Suitable catalysts are hydrogen, benzoyl, acetyl-benzoyl, dibutyryl, lauryl and succinyl peroxides, peracetic acid, perborates, persulphates and peracetates.  Polymerization may also be effected in bulk in a medium which is a solvent for the monomers but a non-solvent for the polymer or in a solvent for both monomers and polymer.  The granular method may also be employed, using protective colloids, e.g. soluble starch, methylated starch, partially hydrolysed polyvinyl acetate, the sodium salts of polymers or interpolymers of acrylic or methacrylic acid, polymethacrylamide, sodium starch glycollate or sodium celluloseglycollate.  The copolymer may be soluble in dioxan, ketones, esters and chlorinated or aromatic hydrocarbons.  Heat stabilizers, e.g. epichlorohydrin, 1-phenoxy-2,3-epoxypropane, 1-p-tolyl-2,3-epoxy-propane, ethylglycidate, cadmium, copper, lead and manganese oleates, linoleates, stearates, recinoleates, palmitates, and laurates, 4 - cyclohexylmorpholine, glycine, leucine, alanine, N-octyl ester of C-dimethylglycine and monocarboxylic acid amides and light-stabilizers, e.g. eugenol, alkyl and aryl salicylic acid esters and guaiacol, plasticizers, fillers, pigments, dyes, natural and synthetic resins may be added.  The products may be used for making films, which may be cold-drawn or rolled to improve their strength, fibres, coatings and adhesives.  U.S.A. Specifications 1,967,225 and 2,173,066 are referred to.

Abstract: 912,329. Control of A.C. motors. SMERALOVY ZAVODY, NARODNI PODNIK. May 14, 1960, No. 17108/60. Class 38 (3). An inching control for a motor comprises a main contactor 3, energized by a push 5 and de-energized when an auxiliary contactor 6 is operated by the closing of contacts 3a on the main contactor. The time for which the motor remains energized is adjusted by varying the travel of either or both contactors 3 and 6. If the push 5 is held closed the inching cycle is repeated indefinitely, but this may be avoided by closing a switch 9 which, together with an auxiliary contact 6a, shunts the contact 3a so that contactor 6 remains energized at the end of one cycle and until the push 5 is released.
