摘要:
The present invention relates to a composition comprising more than 25 weight % (based on the weight of the composition) of one or more ethylene polymers having an Mw of 20,000 g/mole or more and at least 0.1 weight % of a liquid hydrocarbon modifier where the modifier has: 1) a viscosity index of 120 or more, and 2) an kinematic viscosity of 3 to 3000 cSt at 100° C., and 3) a pour point of −10° C. or less, and 4) a flash point of 200° C. or more; and wherein the modifier contains less than 5 weight % of functional groups selected from hydroxide, aryls, substituted aryls, halogens, alkoxys, carboxylates, esters, acrylates, oxygen, nitrogen, and carboxyl, based upon the weight of the modifier.

Isotactic polypropylene ethylene-propylene copolymer blends and in-line processes for producing. The blends may have between 1 and 50 wt % of isotactic polypropylene with a melt flow rate of between 0.5 and 20,000 g/10 min and a melting peak temperature of 145° C. or higher, and wherein the difference between the DSC peak melting and the peak crystallization temperatures is less than or equal to 0.5333 times the melting peak temperature minus 41.333° C., and between 50 and 99 wt % of ethylene-propylene copolymer including between 10 wt % and 20 wt % randomly distributed ethylene with a melt flow rate of between 0.5 and 20,000 g/10 min, wherein the copolymer is polymerized by a bulk homogeneous polymerization process, and wherein the total regio defects in the continuous propylene segments of the copolymer is between 40 and 150% greater than a copolymer of equivalent melt flow rate and wt % ethylene polymerized by a solution polymerization process.
