Abstract
One or more 1-butene polymers and uses thereof. The 1-butene polymer may be used as a viscosity modifier, flexibilizer, dispersing aid, and/or impact modifier for polymer compositions, such as those including polypropylene. The 1-butene polymer may also be used as a carrier for additives, such as fluorinated additives. Articles may be made that include the 1-butene polymer, polypropylene, and pigments.
Claims13
A composition comprising:
- a 1-butene polymer;
- a pigment;
- and
- a polypropylene;
- wherein the 1-butene polymer is present in the composition at an amount of about 5% to about 20% by weight, based on the weight of the composition,
- wherein the pigment is present in the composition at an amount of about 10% to about 45% by weight, based on the weight of the composition;
- and
- wherein the polypropylene is present in the composition at an amount of about 25% to about 85% by weight, based on the weight of the composition.
A method of dispersing a pigment and/or filler in a polymer composition, the method comprising
- providing a polymer composition comprising a pigment, a filler, or a combination thereof;
- and
- contacting the polymer composition with a non-blooming dispersion aid to form a modified polymer composition, wherein the non-blooming dispersion aid comprises a 1-butene polymer;
- wherein the polymer composition has one or more surface characteristics that are substantially identical to one or more surface characteristics of the modified polymer composition.
A method of modifying a polymer composition, the method comprising:
- providing a polymer composition comprising a pigment, a filler, or a combination thereof, wherein the pigment, the filler, or a combination thereof have a first propensity to agglomerate;
- contacting the polymer composition with a 1-butene polymer to form a modified polymer composition, wherein the pigment, the filler, or a combination thereof have a second propensity to agglomerate in the modified polymer composition, wherein the second propensity to agglomerate is less than the first propensity to agglomerate.
