Patent GB-1093238-A (GB)
Title: Process for producing a cellular product from expanded pearls of synthetic resin
IPC: B29C43/22
Filed: 1966-04-01
Abstract: A cellular synthetic resin product is made from expanded pearls by heating the latter to their softening temperature, compressing to impart the required thickness and final density of the product and cooling under compression sufficient to maintain the thickness.  The beads can be heated by hot air or by steam under pressure.  During compression, the pearls are kept at the temperature reached during heating. The apparent density must be selected in dependence on the final density of the product required.  For a given final density the most favourable ratio between it and the apparent density is from 0.4 to 0.6, preferably 0.5.  The density of the expanded pearls used is not more than 5 kg/m.3.  The process may be carried out continuously or discontinuously.  When the process is carried out discontinuously the expanded pearls are introduced into a mould having a perforated bottom and a movable perforated cover The beads are heated by blowing air through the mould at a temperature higher than the softening temperature of the beads, compressed by lowering the cover, and cooled.  To carry out the continuous process the beads are introduced from a hopper between two conveyer belts and are heated by hot air. This first pair of conveyers may be parallel or slightly inclined to one another to effect some compression of the beads.  The beads then pass between a second pair of belts which are parallel and more narrowly spaced than the first pair so that the beads are compressed. The beads are heated by hot air in the first section of the space between the second pair of belts and cooled in the second section. The only example given is of the production of a cellular synthetic product from expanded polystyrene beads.

Specified unsaturated compounds are butadiene, isoprene, vinyl esters, allyl alcohol, vinyl ethers, ethylene, propylene, butylene, isobutylene, styrene and alkyl- and halo-styrenes, acrylic acid esters, methacrylic acid esters, e.g. methyl methacrylate, acrylonitrile, vinyl chloride, vinylidene chloride, tetrafluorethylene and trifluorochlorethylene.  Specified hydrocarbon compounds (a) are diethyl tin, tetraethyl tin, hexaphenyl distannane, tetraethyl lead, tri-n-butyl phosphine, triphenyl phosphine, tribenzyl phosphine, triphenyl arsine, triethyl bismuth and substitution products of iron and nickel carbonyls such as ((C6H5)3P)2Ni(CO)2.  The hydrocarbon radicals may be unsaturated and may be partly replaced by hydrogen, halogen or hydroxyl groups. Specified halogen compounds (b) are carbon tetrachloride, chloroform, methylene chloride, hexachlorethane, trichlorobromomethane, trifluoroiodomethane, ethyl chloride, butyl bromide, tert-butyl chloride, tert-butyl bromide, triphenylchloromethane, monochlorocyclohexane, 1,4-dibromocyclohexane, monochlorobenzene, 1,2-dichlorobenzene, ethylene bromhydrin, trichloracetic acid, trichloracetonitrile and the acid chlorides and bromides of acetic, propionic, cyclohexylic, benzoic and terephthalic acids. The reaction may be effected, if desired continuously, in aqueous emulsion or suspension, or in the presence of inert solvents and diluents, e.g. hexane, octane, gasoline fractions, cyclohexane and benzene.  The telomers may be filtered off and washed with organic liquids, e.g. methanol, ethanol, acetone, dioxane and tetrahydrofurane, which may contain compounds to remove catalyst residues, e.g. oxalic, tartaric, hydrochloric and sulphuric acids, and wetting agents.  The telomers may be used in floor polishes and in moulding powders.
