Abstract
The present invention relates to a composition comprising 1) from 1 to 98 weight % of a first propylene polymer having a melting point of 100° C. or more, 2) from 5 to 98 weight % of a second propylene polymer having a heat of fusion of 70 J/g or less and a tacticity index of 75% or more, 3) from 0.5 to 75 weight % of a non-functionalized plasticizer (“NFP”) having a viscosity index of 120 or more, based upon the weight of the first polymer, second polymer, and the NFP, and articles therefrom
Claims152
A composition comprising 1) from 1 to 98 weight % of a first propylene polymer having a melting point of 100° C. or more, 2) from 5 to 98 weight % of a second propylene polymer having a heat of fusion of 70 J/g or less and a tacticity index of 75% or more, 3) from 0.5 to 75 weight % of a non-functionalized plasticizer (“NFP”) having a viscosity index of 120 or more and a pour point of −10° C. or less, based upon the weight of the first polymer, second polymer, and the NFP.
A molded or extruded article comprising a blend comprising:
- 1) a first propylene polymer having a melting point of 100° C. or more, 2) a second propylene polymer having a heat of fusion of 70 J/g or less and a tacticity index of 75% or more, and 3) a non-functionalized plasticizer where the non-functionalized plasticizer has:
- a) a flash point of 200° C. or more and b) a kinematic viscosity of 35 cSt or more at 100° C. or pour point of −25° C. or less.
A film comprising a blend comprising:
- 1) a first propylene polymer having a melting point of 100° C. or more, 2) a second propylene polymer having a heat of fusion of 70 J/g or less and a tacticity index of 75% or more, and 3) a non-functionalized plasticizer where the non-functionalized plasticizer has:
- a) a flash point of 200° C. or more and b) a kinematic viscosity of 35 cSt or more at 100° C. or pour point of −25° C. or less.
A fiber comprising a blend comprising:
- 1) a first propylene polymer having a melting point of 100° C. or more, 2) a second propylene polymer having a heat of fusion of 70 J/g or less and a tacticity index of 75% or more, and 3) a non-functionalized plasticizer where the non-functionalized plasticizer has:
- a) a flash point of 200° C. or more and b) a kinematic viscosity of 35 cSt or more at 100° C. or pour point of −25° C. or less.
