Polyethylene compositions with improved optical properties

A polyethylene composition comprising:

• at least 50% by wt. of at least one polyethylene polymer chosen from a linear low density polyethylene polymer (LLDPE), a low density polyethylene polymer (LDPE), a high density polyethylene polymer (HDPE), or combinations thereof;
• and
• 0.001 to 2% by wt nucleating agent comprising a structure of formulas (I), (II), or (III):
• wherein R1 and R2 comprise the same or different moieties chosen from:
• C1-C20 alkyl unsubstituted or substituted by one or more hydroxy;
• C4-C20 alkenyl unsubstituted or substituted by one or more hydroxy;
• C2-C20 alkyl interrupted by oxygen or sulfur;
• C3-C12 cycloalkyl unsubstituted or substituted by one or more C1-C20 alkyl;
• (C3-C12 cycloalkyl)-C1-C10 alkyl unsubstituted or substituted by one or more C1-C20 alkyl;
• bis[C3-C12 cycloalkyl]-C1-C10 alkyl unsubstituted or substituted by one or more C1-C20 alkyl;
• a bicyclic or tricyclic hydrocarbon radical with 5 to 20 carbon atoms unsubstituted or substituted by one or more C1-C20 alkyl;
• phenyl unsubstituted or substituted by one or more radicals selected from C1-C20 alkyl, C1-C20 alkoxy, C1-C20 alkylamino, di(C1-C20 alkyl)amino, hydroxy and nitro;
• phenyl-C1-C20 alkyl unsubstituted or substituted by one or more radicals selected from C1-C20 alkyl, C3-C12 cycloalkyl, phenyl, C1-C20 alkoxy and hydroxy;
• phenylethenyl unsubstituted or substituted by one or more C1-C20 alkyl;
• biphenyl-(C1-C10 alkyl) unsubstituted or substituted by one or more C1-C20 alkyl;
• naphthyl unsubstituted or substituted by one or more C1-C20 alkyl;
• naphthyl-C1-C20 alkyl unsubstituted or substituted by one or more C1-C20 alkyl;
• naphthoxymethyl unsubstituted or substituted by one or more C1-C2 alkyl;
• biphenylenyl, flourenyl, anthryl;
• a 5-to-6-membered heterocylic radical unsubstituted or substituted by one or more C1-C20 alkyl;
• a C1-C20 hydrocarbon radical containing one or more halogen;
• or tri(C1-C10 alkyl)silyl(C1-C10 alkyl);
• wherein, when the polyethylene composition is used to form an article, the article has a haze value reduction of at least 15% when compared to an article having the same polyethylene polymer but free of the nucleating agent.
