Summary:Un copolímero ionomérico segmentado, el cual, cuando se mezcla con una poliolefina, mejora la resistencia a la flexión. A segmented copolymer comprising a non-polar polyolefin trunk with a chain grafted thereto by a covalent bond. The weight ratio of the chain to the trunk is from 1:9 to 4:1. The chain comprises acid monomer, vinyl aromatic monomer and methacrylic ester. At least some of the acid units bear a charge which is associated with non-polymeric counter-ions such as calcium or magnesium. The segmented copolymer imparts high resistance to sagging without increasing melt viscosity to polyolefins.
