USE OF A CARBOXYLIC ACID ANHYDRIDE TO MANUFACTURE A POLYOLEFIN MOULDING COMPOSITION

A polyolefin moulding composition which contains from 0.01 to 3% by weight, based on the polyolefin, of a carboxylic anhydride in free or bound form is distinguished by significantly lower corrosive properties towards metals and a low tendency toward yellowing, compared with the prior art. A particu...

Beschreibung
Zusammenfassung:	A polyolefin moulding composition which contains from 0.01 to 3% by weight, based on the polyolefin, of a carboxylic anhydride in free or bound form is distinguished by significantly lower corrosive properties towards metals and a low tendency toward yellowing, compared with the prior art. A particularly effective anhydride is maleic anhydride in free form, in the form of a copolymer with an olefin or in the form of a graft polymer on a polyolefin.
