Disclosed are rheology modifiers comprising compositionally disperse polymeric compositions and/or crystallinity disperse polymeric compositions that may be useful in modifying the rheological properties of lubrication fluids, and methods for making such compositions. The compositionally disperse polymeric composition are formed from at least two discrete compositions of ethylene copolymers. The crystallinity disperse polymeric composition are formed from ethylene copolymers having at least two discrete values of residual crystallinity.

The present invention relates to plasticized polyolefin compositions comprising a polyolefin and a non-functionalized hydrocarbon plasticizer.

Plasticized polyolefin compositions

Provided is a heat-seal resin. The resin includes 5 wt % to 95 wt % of a first copolymer and 95 wt % to 5 wt % of a second copolymer based on the total weight of the resin. The first copolymer and the second copolymer together are 90 wt % or more of the total weight of the resin. The first copolymer includes a first monomer of an alphaolefin of 2 to 4 carbon atoms and a second monomer selected from a second monomer of an alphaolefin of 2 to 8 carbon atoms. The first monomer and the second monomer of the first copolymer are different. The first copolymer has an MFR of from 5 to 1000 g/10 minutes and a Tof 66&#xb0; C. to 80&#xb0; C. The second copolymer includes a first monomer of an alphaolefin of 2 to 4 carbon atoms and a second monomer selected from a second monomer of an alphaolefin of 2 to 8 carbon atoms. The first monomer and the second monomer of the second copolymer are different. The second copolymer has an MFR of from 0.5 to 5 g/10 minutes and a Tof 45&#xb0; C. to 66&#xb0; C., wherein the first copolymer has an MFR of at least 2 g/10 minutes greater and a Tof at least 10&#xb0; C. greater than the second copolymer. There is also a package formed partly or entirely of the resin.
