Title: Improvements relating to irradiated polyethylene and products therefrom
IPC: C08J7/046
Filed: 1955-10-27
Abstract: Polyethylene which has been irradiated with high energy electrons is coated with a uniform, firmly adhering resinous layer to improve its stability to heat.  This coating may consist of phenol-aldehyde resins which may be modified with oils, alkylated phenols, e.g. tertiary butyl phenol, or rosin; of alkyd resins modified with oils, rosin or phenol-aldehyde resins; of phenolaldehyde-modified polyvinylal resins or of ethoxylene resins.  Specific examples comprise a solution of a rosin-and-linseed-oil-modified glyceryl-phthalate resin which may be further modified with formaldehyde and p-tertiary butyl phenol resin, and a soya-oil-modified alkylated phenol-formaldehyde resin dissolved in xylene and petroleum spirit.  Examples of the drying, semi-drying, non-drying and fatty oils and of the fatty oil acids used in modifying the above resins are linseed oil, chinawood oil, castor oil, soya bean oil, oiticica oil, linseed and coconut oil acids, palmitic acid, stearic acid and oleic acid.  Driers such as iron and manganese octoates and naphthenates, tin oleate and cobalt naphthenate may be incorporated in the coating and suitable solvents for the coatings include petroleum spirits, xylene, liquid aliphatic hydrocarbons, butanol, and aliphatic acylates such as amyl acetate. The polyethylene may be stabilized before irradiation by the addition of, for example, N,N1-dinaphthyl-p-phenylenediamine.  The product of the invention may be in the form of sheets (which may be slit into tapes), bottles, containers or gaskets.  Such articles or polyethylene insulated conductors, such as slot liners in motors, taped coils in motors or generators, layer insulation in coils and transformers or protective tapings may be formed from irradiated polyethylene and subsequently coated or may be formed from unirradiated polythene and subsequently irradiated and then coated. Preformed articles may be given a high dose of radiation, but polyethylene is irradiated and subsequently milled or moulded, smaller dosage is given.  Fillers such as carbon black, silica aerogel or fumed silicas may be incorporated before or after irradiation or before or during milling.

Title: A process for preparing a diels-alder adduct of hexachlorocyclopentadiene and acetylene
Inventor: ANDERSON JOHN
IPC: C07C17/30
Filed: 1958-09-26
Abstract: 1,2,3,4,7,7 - Hexachlorobicyclo - (2,2,1) - heptadiene-2,5 (Compound B) is prepared from hexachlorocyclopentadiene (hex) and acetylene by a process which comprises (a) dissolving acetylene in hex under pressure at a temperature below the reaction temperature, (b) compressing the resulting solution without substantially increasing the temperature to a pressure which exceeds the total vapour pressure of the solution at the reaction temperature, and (c) heating the solution to the reaction temperature while maintaining the high pressure and maintaining that high temperature until the desired degree of conversion has been reached.  In a preferred form, a 40 to 50 mol. per cent of acetylene solution is prepared by dissolving acetylene in hex at -20 DEG  to 10 DEG  C. and a pressure of 250-350 p.s.i.g. and the solution is then compressed to at least 2000 p.s.i.g. with a pump having a cooling jacket and finally heated to a reaction temperature of 150 DEG  to 175 DEG  C.  The reactor, which may be an elongated externally heated coil, is preferably completely filled with the solution so that the reaction takes place in a homogeneous liquid phase.  The product contains predominantly Compound B and excess hex which can only be separated with difficulty by distillation.  The process may be carried out in a plurality of stages where the product from the first stage is cooled and resaturated with acetylene and recycled so that substantially complete conversion of hex is obtained in four stages.  Alternatively and preferably, the first stage product containing no more than 50 mol. per cent of Compound B is treated with bicyclo-(2,2,1) - heptadiene - 2,5 so as to conver the unreacted hex into aldrin-(1,2,3,4,10,10-hexachloro - 1,4,4a,5,8,8a - hexahydro - 1,4 - endoexo - 5,8 - dimethano - naphthalene) by DielsAlder condensation, and Compound B is then separated from the aldrin by distillation. Examples of both processes are given.  Specifications 692,545, 714,830, 745,079, 794,948 and 801,677 are referred to.
