When polymerized with certain chiral initiators, optically active polychloral whose optical activity is based on macromolecular asymmetry was prepared. Polymerizable and Polymer Bound Ultraviolet Stabilizers Preserving the physical and mechanical properties of polymers that are exposed to the environment is a most demanding challenge and essential for the long term utilization of synthetic polymers. Head to Head Polymers Head to head linkages in commodity polymers sometimes exist in significant amounts and can influence some of the properties of these polymers. Over the years we have synthesized a number of pure head to head polymers and have studied their structural characteristics and their thermal, photo-oxidative, and blending behavior. Many polymers are known to exist as mixtures with most molecular weight distribution.
Polymers prepared by living polymerization have narrow distributions.
Recently, uniform polymers, polymers of a single molecular weight have been isolated. These uniform polymers still consist of mixtures macromolecules that have many species of different isotope molecular weights whose composition depends on the numbers of monomer units and the terrestrial isotope composition. We have recently become involved in the calculation of uniform polymers of isotopically pure uniform polymers. One specific problem is the preparation and preservation of in art objects based on Oriental Lacquers.
