Abstract: This invention relates to plastoelastomeric polyolefinic compositions comprising an intimate mixture of the following components, in the indicated percentages by weight:A) 10-50% of non cross-linked polypropylene;B) 2-10% of ethylene/propylene/(diene)non cross-linked elastomeric copolymer,C) 30-40% of polymeric product which is insoluble in xylene at 135.degree. C., comprising polypropylene and ethylene/propylene/(diene) copolymer, andD) 5-58% of an extender oil.This invention also relates to a process for preparing the above compositions, which consists in subjecting to vulcanization under dynamic conditions a mixture comprising, in % by weight:A) 20-80% of polypropylene,B) 80-20% of ethylene/propylene/(diene) elastomeric copolymer,C) 0.1-10%, referred to such copolymer, of a peroxide,D) 5-60%, referred to such peroxide, of a furan derivative as a cross-linking coadjuvant.and in adding, after vulcanization, the extender oil in an amount ranging from 6 to 100% calculated on the vulcanized product.

Abstract: A composition comprises a carboxylic acid compound which contains at least three carbon atoms together with an organic sulphur-containing acid or salt of such an cid. The carboxylic acid may be an aliphatic diacid such as succinic acid. The sulphur-containing acid may be a sulphonic or sulphuric acid derivative such as the sodium salt of an alkyl sulphonic acid or of sulpho-succinic acid. The composition may be incorporated into an olefin polymer. The composition may be obtained by conventional powder blending or, for a polymer composition, melt blending techniques. Preferred polymer compositions have an increased clarity and a reduced level of haze compared to the polymer alone or the polymer containing only the carboxylic acid.

Abstract: The present invention relates to low odor coalescing aids for latex paints comprising 2-alkyl-1,3-hexanediol alkyl esters ##STR1## These coalescing aids are incorporated into latex paints in an amount sufficient to speed curing and lower curing temperatures.
