ABSTRACT:
A blend of at least one carboxylic acid which is an aromatic acid, a hydroxy-acid, or a polycarboxylic acid or the anhydride of such an acid and a polypropylene/unsaturated carboxylic acid or anhydride 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. A particularly good effect is obtained with cyclic anhydrides and those acids capable of forming such anhydrides. The graft copolymer is preferably a polypropylene/maleic anhydride graft copolymer.
