    Abstract: Polyepoxides are cured by basic polyamides obtained by reacting a molar excess of a primary and/or secondary polyamine with an adduct of a natural resin acid with an a ,b -ethylenically unsaturated carboxylic acid and/or a derivative thereof which will form amide groups. Preferred adducts are of maleic, fumaric, itaconic, acrylic, aconitic or citraconic acid with colophony or with pimaric or abietic acids and their derivatives, whilst the preferred amines are polyalkylenepolyamines. Many polyepoxides are specified. Conventional hardeners or accelerators for the curing of polyepoxides may also be present in the curable mixtures as may be solvents. The curable compositions are useful as lacquers, moulding compositions, casting or laminating resins, dip resins, adhesives and encapsulating compositions. Polyamides are prepared by reacting a colophony acrylic acid adduct with diethylenetriamine or diethylenetriamine and 1,3-bisaminomethylbenzene under nitrogen.ALSO:Sheet steel and glass sheets are painted with lacquers comprising a polyepoxide, a polyamide derived from a molar excess of a polyamine and an adduct of an a , b -ethylenically p unsaturated carboxylic acid with a natural resin acid and an organic solvent (see Division C3).

    Abstract: A self-extinguishing plastic composition comprises (a) a polymer or copolymer of styrene or a -methyl styrene; (b) an organic chlorine compound in amount sufficient to provide a chlorine content of 2 to 7% by weight of the composition; (c) a complex MexAry- 1(CO)z- 1, wherein X and Y are 1,2 or 3, Z is from 1 to 13, (Y - 1) + (Z - 1) is from 2 to 12; Me is Cr, Mn, Fe, Co, Ni, Mo, Tc, Ru, Rh, Pd, W, Re, Os, Ir or Pt; and Ar is a substituted or unsubstituted cyclopentadienyl or benzene radical, and, optionally (for making the composition expandable; (d) a volatile liquid expanding agent which does not dissolve the polymer and which has a boiling point below the softening point of the polymer. The polymer may be a copolymer with acrylonitrile, butadiene, an ester of acrylic or methacrylic acid, vinyl carbazole or divinyl benzene. Component (b) may be chlorinated polyvinyl chloride, chlorinated polyisobutylene, chlorinated polystyrene, chlorinated paraffins, hexachlorocyclododecane, hexachlorocyclopentadiene, hexachloroendomethylene tetrahydrophthalic acid, tetrachlorobutyrolactone or tetrachlorobutanediol diacetate. Many suitable complexes (c) are specified, those used in the examples being ferrocene and various derivatives thereof, nickelocene, dibenzene chromium, carbonyls of Mn, Mo and Co, chlorobenzene chromium tricarbonyl and various cyclopentadienyl carbonyl complexes of Cr, Mo, Co, Ni and Fe. The expanding agent (d) may be a hydrocarbon or halohydrocarbon and in the examples pentane and hexane are used. The compositions may be obtained by lead polymerization of the monomer in the presence of the ingredients (b) and (c) \sB (d), or all the components may be dissolved in an organic solvent immiscible in water (e.g. methylene chloride or dichloroethylene), following which the solution is poured into water containing a protective colloid. The products find application as moulded articles, e.g. sheet, and as coatings.

    Abstract: 1,2-5,6-9,10-triepoxycyclododecane is prepared by the reaction of cyclododecatriene-(1,5,9) with peroxy acids or other peroxy compounds, preferably in the presence of inert organic solvents.ALSO:A hardening casting resin comprises a mixture of (i) 1, 2-5, 6-9, 10-triepoxycyclododecane with or without at least one other compound having more than one epoxy group, and (ii) a curing agent for compounds having more than one epoxy group, with or without (iii) up to 20% by weight of (i) and (ii) of a liquid substance other than a polymerizable ethylenically unsaturated substance; polymerizable liquid ethylenically unsaturated substances (iv) may be added in quantities up to 30% by weight of (i) and (ii) Compounds specified are:-(i) the polyglycidyl ethers of ethyleneglycol, glycerine, pentaerythritol and bisphenol A, vinyl cyclohexene dioxide, and 1, 2-5, 6-diepoxycyclooctane; (ii) o-, m- and p-benzene dicarboxylic acids, phthalic and maleic anhydrides, 1, 4-diaminobenzene and 4, 41-3, 31-dimethyldicyclohexylmethane, with or without sulphuric or phosphoric acids, AlCl3, BF3, FeCl3, ZnCl2, SnCl4, NaOH, KOH, quaternary ammonium compounds and BF3-amine complexes; (iii) water, aqueous solutions of simple alcohols or ketones, liquid hydrocarbons, or simple alcohols, ketones or ethers; (iv) styrene and acrylic or methacrylic esters of monohydric lower aliphatic alcohols. Fillers, glass fibres and pigments may also be added.
