    Abstract: Provided are methods forming polymers. The methods include, for example, tandem carbonylation and polymerization reactions, where epoxides are catalytically carbonylated to form lactones and the lactones catalytically polymerized to form polymers without the need to isolate or purify the lactone intermediate. Also provided are methods for catalytically polymerizing beta-propiolactone. Homopolymers and copolymers can be formed using the methods disclosed herein.

    Abstract: Isotactic polyethers, methods of making polyethers, and uses of polyethers. The polyethers have a chain transfer group formed from a chain transfer agent. The methods of making the polyethers use monoalcohol chain transfer agents or multifunctional chain transfer agents. The polyethers can be used in materials, such as polyurethanes, elastomers, thermoset plastics, and thermoplastics, and as non-ionic surfactants.

    Abstract: The present invention relates to olefin polymerization catalysts including a novel phenoxyaminetitanium(II) alkene complex, rac-Lig2 TiBn, which is inactive for olefin polymerization upon benzyl abstraction, treatment with ethylene leads to the formation of a stable titanacyclopentane complex (rac-Lig2(CH2)2TiBn). Six-membered metallacycle complexes (rac-Lig1ZrBn2-a,b and rac-Lig1HfBn2-a,b) were obtained from reaction of the vinylappended ligand with tetrabenzylzirconium (ZrBn4) or tetrabenzylhafnium (HfBn4). Living and isoselective polymerization of 1-hexene was promoted by rac-Lig1HfBn2- a,b/B(C6F5)3 at 0°C, while rac-Lig1ZrBn2-a,b/B(C6F5)3 catalyzed the living and isoselective polymerization of propylene at 0°C. This catalyst system was employed for the synthesis of a diblock copolymer featuring an isotactic polypropylene semicrystalline block and poly(ethylene-co-propylene) amorphous block. Complexes derived from rac-Lig1HfBn2-a,b and rac-Lig1ZrBn2-a,b also served as highly active cyclopolymerization catalysts for 1,5- hexadiene which furnished poly(methylene-l,3-cyclopentane) with a predominance of cis- cyclopentane rings. Lastly, cyclopolymerization of 1,6-heptadiene with rac-Lig1HfBn2- a,b/B(C6F5)3 produced poly(methylene-1,3-cyclohexane) with a nearly perfect cis-isotactic microstructure.
