Patent GB-1075232-A (GB)
Title: Improvements in poly-thio-ethers
Inventor: ETTINGSHAUSEN OTHMAR GEORG
IPC: C08G75/06
Filed: 1964-02-14
Abstract: Linear thioketone polymers are produced by polymerizing monomeric thioketones of the type <FORM:1075232/C3/1> wherein R and R1 are the same or different, and may be alkyl, or aralkyl, radicals, by allowing the temperature of the monomer to rise. Polythioacetones of the formula <FORM:1075232/C3/2> are also claimed per se.  The polymerization is preferably performed at a temperature within the range of 20 DEG  to - 196 DEG  C. The lower the temperature in this range, the larger is the molecular weight of the polymer formed.  A solvent, e.g. an aliphatic or aromatic hydrocarbon, a halogenated derivative thereof, or an acylic, heterocyclic or aromatic ether, may be present.  The thioketone monomers may be co-polymerized with cyclic ethers, oxycyclobutanes, lactams, isocyanates, nitriles, styrene or its derivatives, vinyl compounds, allylic compounds, acrylic esters or mono-, bi- or poly functional chain transfer agents.  The polymers may be treated with end-capping agents, e.g. acid anhydrides, carboxylic acids or their substituted phenyl esters, acetals, isocyanates, nitriles, ketenes, or diazo compounds, and may incorporate nitrogen-containing organic antioxidants. The thioketone polymers or co-polymers may be mechanically or physically mixed with other polymers, e.g. polyamides and may have pre-formed polymers, e.g. polyalkylene glycols, epoxide polymers or diolefins, added to them to form block or graft co-polymers.ALSO:Novel thioketone monomers of the type:  <FORM:1075232/C2/1> where R and R1 are the same or different, and may be alkyl, or aralkyl, radicals are prepared by heating trimeric thioketones of the formula <FORM:1075232/C2/2> to a depolymerization temperature within the range 175 DEG  to 450 DEG  C., and cooling the vapours to a temperature below the melting-point of the monomer.  The heating may be effected by passing the trimeric thioketone over a heated surface, which may be wire, glass or silica, and the vapour is then cooled by a series of cold traps, preferably to between -40 DEG  and -196 DEG C. and the monomer is preferably collected at a reduced pressure, e.g. 0.1 to 5 mm. Hg.  The trithioacetone used is obtained by reacting acetone with hydrogen sulphide in the presence of zinc chloride or hydrogen chloride, or by passing gaseous hydrogen chloride into a hexane solution of propane-2,2-dithiol, itself formed from di-methyl formamide and hydrogen sulphide in the presence of morpholine.  The required symmetrical trimer may be purified by treatment with sodium plumbite or p-benzoquinone, or by recrystallization from hexane. The thio-ketone monomers readily polymerize (see Division C3).

Abstract: 1447566 Calcium carbonate IMPERIAL CHEMICAL INDUSTRIES Ltd 30 Jan 1975 [14 Feb 1974] 6686/74 Heading C1A Precipitated calcium carbonate, usable as a filler in paints, plastics and rubber by virtue of its low hardness, is prepared by carbonating an aqueous suspension of Ca(OH) 2  with the addition of a complex forming agent for Ca ions after the "primary nucleation stage" (i.e. that stage during the carbonation at which spontaneous nucleation of CaCO 3  first occurs, its onset being generally accompanied by a rapid increase in the rate of precipitation of CaCO 3 ). The carbonation may comprise the conventional two stage process including an ageing step viz. a first carbonation of a Ca(OH) 2  slurry to a pH of 8-10 followed by ageing and then a second carbonation until the pH falls to 7-8. The complexing agent may be used in conjunction with a 12-20C fatty acid or salt (e.g. stearic acid or NH 4  stearate). Exemplified complexing agents are hydroxy carboxylic acids, e.g. citric acid, malic acid; polyhydroxy carboxylic acids, e.g. gluconic, tartaric acid or precursors of such acids, e.g. gluconolactone; oxyacids, polycarboxylic acids, mono and polysaccharides, polyhydroxy alcohols, hydroxy sulphonic acids, aminopolycarboxylic acids and polyphosphates.
