Polyolefin masterbatch and composition suitable for injection molding |
摘要 |
A masterbatch composition comprising (percent by weight): A) 50%-90% of a crystalline polypropylene component comprising: AI) from 25% to 75% of a fraction having a melt flow rate MFRI of from 0.1 to 10 g/10 min.; and AII) from 75% to 25% of a fraction having a melt flow rate value MFRII equal to or lower than 100 g/10 min.; wherein the ratio MFRI/MFRII is from 5 to 60; and B) 10%-50% of a copolymer component of ethylene and at least one C3-C10 α-olefin, containing from 15% to 50% of ethylene; said masterbatch composition having a value of the intrinsic viscosity [&eegr;] of the fraction soluble in xylene at room temperature equal to or higher than 3.5 dl/g, is added to polyolefin materials to obtain final compositions suitable for injection molding.
