Abstract: Catalyst systems for olefin polymerization include a metal-ligand complex of a general formula (I). The metal-ligand complex of formula (I) is a transition metal complex of titanium, zirconium, or hafnium, in which the transition metal is coordinated with a biaryl phenoxy ligand structure. Olefin polymerization processes include contacting ethylene and optionally one or more (C3-C12) alpha-olefins in the presence of the catalyst system to produce an ethylene-based polymer or copolymer.

Abstract: Polyol compositions that contain imide groups are prepared by producing imide compounds from trimellitic anhydride and an aromatic aminoacid or an aromatic diamine, then esterifying the imide compounds with one or more polyols that have hydroxyl equivalent weights of 30 to 500. Aromatic carboxylic acid derivatives may be present during the esterification step to produce polyol compositions that contain species that have imide groups, and other species that do not have imide groups. The polyol compositions are useful in making isocyanate-based polymers, in particular polyurethane and/or polyurethane-isocyanuranate foams. The presence of the imide groups in the isocyanate-based polymers imparts fire retardant properties.

Abstract: According to one or more embodiments of the present disclosure, a coated film may be made by a process that may include applying an uncured polyurethane precursor between a polyolefin film and a release liner such that a first surface of the release liner is in contact with the uncured polyurethane precursor, curing the uncured polyurethane precursor to form a cured polyurethane layer positioned between the polyolefin film and the release liner, and removing the release liner to form the coated film comprising the polyolefin film and the cured polyurethane layer. The first surface of the release liner may have an optical finish. The curing may impart an optical finish to the cured polyurethane layer substantially similar to the optical finish of the first surface of the release liner.
