대표청구항 ▼

1. A composition comprising: from 50 to 99.99 weight percent based on the total weight of the composition of a melt-processable thermoplastic hydrocarbon polymer;a silicone-containing polymeric process additive effective to reduce melt fracture, wherein the silicone-containing polymeric process additive is selected from the group consisting of polydiorganosiloxane polyamide polymers and silicone-polyurethane polymers; anda synergist that improves the efficacy of the process additive to reduce melt fracture; wherein the synergist is present in an amount of from 10 wt % to 50 wt % based on the total amount of synergist and process additive. 2. The composition of claim 1, wherein the hydrocarbon polymer is selected from the group consisting of: a polyethylene homopolymer, a polypropylene homopolymer, a modified polyethylene polymer, a modified polypropylene polymer, a polyethylene copolymer, a polypropylene copolymer, and a combination thereof. 3. The composition of claim 1, wherein the hydrocarbon polymer is selected from the group consisting of a high density polymer and a low density polymer. 4. The composition of claim 1, wherein the hydrocarbon polymer is a linear low density polyethylene. 5. The composition of claim 1, wherein the silicone-containing polymeric process additive is a silicone-polyurethane. 6. The composition of claim 1, wherein the silicone-containing process additive is a silicone-polyamide selected from the group consisting of: a copolymer comprising at least two repeat units of Formula I: wherein each R1 is independently selected from the group consisting of: an alkyl group, a haloalkyl group, an aralkyl group, an alkenyl group, an aryl group, an alkoxy group, and a halogen;each Y is independently selected from the group consisting of: an alkylene group, aralkylene group, and a combination thereof;G is a divalent group;each B is independently selected from the group consisting of: a covalent bond, an alkylene group having from 4 to 20 carbons atoms, an aralkylene group, an arylene group, and a combination thereof; n is an integer of 0 to 1500; and p is an integer of 1 to 10; andeach R3 is independently selected from the group consisting of: an alkyl group, a haloalkyl group, an aralkyl group, an alkenyl group, an aryl group, an alkoxy group, and an alkylene group having 2 or more carbon atoms forming a heterocyclic ring that includes the R3 groups, the nitrogen atoms, and G. 7. The composition of claim 1, wherein the silicone-containing process additive is present in a weight percent of from 0.01 wt % to 3.0 wt % based on the total weight of the composition. 8. The composition of claim 1, wherein the total weight of the process additive and the synergist is from 0.01 wt % to 5.0 wt % based on the total weight of the composition. 9. The composition of claim 1, wherein the hydrocarbon polymer is present in a weight percent of from 99.99 wt % to 95 wt % based on the total weight of the composition. 10. The composition of claim 1, wherein the synergist is selected from the group consisting of i) a silicone-polyether copolymer; ii) an aliphatic polyester; iii) an aromatic polyester; iv) a polyether polyol; v) an amine oxide; vi) a carboxylic acid; vii) a fatty acid ester; and vii) a poly(oxyalkylene) polymer. 11. The composition of claim 1, wherein the synergist is selected from (a) a polyethylene glycol; and (b) a polycaprolactone. 12. The composition of claim 1, wherein the synergist is a polyethylene glycol. 13. The composition of claim 1, wherein the synergist is present in an amount of from 10 wt % to 30 wt % based on the total amount of synergist and process additive. 14. The composition of claim 1, further comprising a hindered amine light stabilizer selected from compounds having the general formula: wherein R2 is selected from the group consisting of H and a C1 to C6 alkyl group, z is an integer of from 1 to 5, and R1 is an organic moiety having a valency of z.
