ABSTRACT:
A blend of at least one boron, phosphorus or sulphur containing acid which may contain amino, hydrocarbyl or hydrocarbylamino substituents and a polypropylene/unsaturated carboxylic acid or anhydridge graft copolymer has adhesive properties similar to those of the graft copolymer alone. The blend is readily produced and can be used in a fibre reinforced thermoplastic material or in blends of an olefine polymer with a different type of polymer such as a polyamide or polyester. Suitable acids include phenyl boric acid, phenylphosphonic acid, diphenylphosphinic acid, sulphanilic acid, toluene sulphonic acid, phenylhydrazine-p-sulphonic acid, d-10-camphor sulphonic acid, orthanilic acid, hypophosphorus acid, sulphosalicylic, and particularly sulphamic acid. The graft copolymer is preferably a polypropylene/maleic anhydride graft copolymer.
