    Abstract: Radical polymerisation of vinyl chloride uses an aqueous suspension containing stopper and also an organic, water-miscible liquid of b.pt. 30-90 deg C. Radical polymerisation of vinyl chloride in aqueous suspension at 20-100 deg C and 5-30 bar involves adding a 10-50 wt.% aqueous suspension of a sterically hindered phenol of mol. wt. above 300 as stopper, to give 0.01-0.2 wt.% phenol and containing 5-15 pts. wt., per 100 pts. wt. suspension, of an organic, water-miscible liquid of b.pt. 30-90 deg C.

    Abstract: A process for internal sizing of paper and paper-like products by adding (A) emulsions of fatty alkyl-diketenes and (B) polyethyleneimine with 20 to 500 ethyleneimine units and/or water-soluble condensation products, which are obtainable by grafting 100 parts by weight of water-soluble polyamido-amines with 20 to 400 parts by weight of ethyleneimine and crosslinking of the ethyleneimine-grafted products by means of difunctional crosslinking agents, to the paper stock and draining of the paper stock with sheet formation leads to diketene sizing which manifests itself within a short time.

    Abstract: De-icing or anti-icing compositions for aircraft, essentially containing glycols, crosslinked polyacrylic acid, a nonionic surfactant composed of alkoxylated C10-C20-alcohols, corrosion inhibitors, a mixture of NaOH and KOH, an oxidation stabiliser and water. The compositions effect a smaller loss of lift owing to an improvement in the flow behaviour on the wings while maintaining a holdover time against refreezing of at least 30 min.

    Abstract: 1. A glycol-based coolant mixture which is free of nitrites and phosphates, containing a) 1 - 5% by weight of an alkali metal salt of acid II see diagramm : EP0283806,P7,F1 where R is a -CH2 -, see diagramm : EP0283806,P7,F2 see diagramm : EP0283806,P7,F3 or CH2 CH2 CH2 group, b) 0.1 - 1% by weight of a silicate of the general formula III (MO)q SiO4-q/2 where M is an alkali metal and q is from 0.4 to 4, c) 0.01 - 0.2% by weight of a silicate stabilizer, d) 0 - 0.5% by weight of an alkali nitrate, e) 0.05 - 0.2% by weight of benzotriazole or tolutriazole, f) 0.5 - 2% by weight of borax, and g) 0.05 - 1% by weight of NaOH, all the percentages being based on the glycol present in the coolant mixture.
