A polymer blend is provided, which includes 100 parts by weight of a first polyolefin, 3 to 100 parts by weight of a thermoplastic polyurethane, and 3 to 10 parts by weight of a modified polyolefin. The modified polyolefin is formed by grafting maleic anhydride or acrylate onto a second polyolefin. The blend can be used to form fiber.

Embodiments of organic peroxide formulations provide longer scorch time protection and require fewer additives. The peroxide formulations may include, for example, at least one organic peroxide, and at least one scorch retardant additive selected from the group consisting of vitamin K1 (phlloquinone), K2 (menaquinone), K3 (menadione), olive leaf oil (oleuropein), and mixtures thereof.

This invention relates to a vehicle headlight assembly comprising: a light source, a housing supporting the light, a bezel equipped over the front side of the housing, and a transparent cover being equipped over the front side of the bezel, wherein the bezel and optionally the housing comprises a thermoplastic resin and a colorant, wherein the colorant is selected from the group consisting of an anthraquinone dye, an amine salt thereof and a mixture thereof.

The invention relates to a hydrogel product comprising glycosaminoglycan molecules as the swellable polymer, wherein the glycosaminoglycan molecules are covalently crosslinked via crosslinks comprising a spacer group selected from the group consisting of di-, tri-, tetra-, and oligosaccharides.

Curable compositions comprise at least one (meth)acrylate monomer; silver; and a photoinitiator system. The photoinitiator system comprises at least one cyclic β-diketone represented by the formula (I) or a tautomer thereof, wherein: R.sup.1 represents H or an organic moiety having from 1 to 32 carbon atoms and optionally 1 to 12 heteroatoms selected from O, N, and combinations thereof; each R.sup.2 independently represents H or an aliphatic group having from 1 to 12 carbon atoms, and up to two of oxygen and sulfur atoms; and n represents 1, 2, or 3; and at least one Type II photoinitiator. Methods of making and using the compositions are also disclosed.
