Zusammenfassung:In order to lighten automobile bumpers and shorten the production cycle, the properties of elastomer-modified polypropylenes were studied. Use of a large amount of reinforced elastomer controlled the growth of micro crystals which formed matrices with amorphous polypropylene, resulting in the increases in crystallinity and fluidity. As a result, high performance elastomer-modified polypropylenes were developed without lowering impact resistance and tensile elongation.
