A compound of Formula (II) and (III), or a mixture of any two or more thereof; wherein M is Ti or Zr; Rat each occurrence is H, F, Cl, Br, I, CN, OR, NRR, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloalkylalkyl, unsubstituted heterocyclyl, or substituted or unsubstituted heterocyclylalkyl; Ris H, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloalkylalkyl, unsubstituted heterocyclyl, or substituted or unsubstituted heterocyclylalkyl; Rand Rare independently H, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocyclylalkyl, or Rand Rmay join to form a heterocyclic ring containing the N to which they are attached; and n'=0-4. Such compounds form optically transparent and/or clear films or particles or may be used to prepare such materials.

Product containing monomer and polymers of titanyls and methods for making same

The invention provides alternatives to traditional polycondensation processes for preparing copolymers. For example, in certain embodiments, the invention provides a process that includes an extrusion step and a solid state polymerization step to prepare high molecular weight block copolymer with a 'hard block' contributed by a macrocyclic polyester oligomer (MPO) and a 'soft block' contributed by a dihydroxyl-functionalized polymer, an oligoether, and/or a dimerized fatty acid (i.e. a polyol). The invention also provides new copolymer compositions made possible by the new processes&#x2014;for example, copolymers of higher molecular weight, copolymers with higher weight ratio of soft block units to hard block units, copolymers made with higher molecular weight polyol, and copolymers with hard block units that are themselves random copolyesters of units contributed by a MPO and a cyclic ester.
