摘要:
Disclosed herein are novel polymer-tethered ligands, metal complexes comprising these ligands, and the use of these complexes as chain transfer catalysts to control the molecular weight of oligomeric and polymeric materials produced in a radical polymerization process. The materials made by the processes disclosed herein have significantly reduced color, making them suitable for a wide range of color-critical end-uses, including automotive coatings.

Improved flame retardant polytrimethylene terephthalate compositions are provided by including a perfluorinated sulfonate salt as a flame retardant additive.
摘要:
One aspect of the invention is a method for making a composite material comprising a porous support and a porous nanoweb comprising: (a) providing a porous support; (b) providing a gelling mixture comprising one or more solvent(s) and one or more organogelator(s); (c) applying the gelling mixture to the porous support; (d) inducing said organogelator(s) to form a nanoweb gel; and (e) removing the solvent(s) from the nanoweb gel to provide a dry porous nanoweb coating on said porous support; wherein the one or more solvent(s) is a supercritical fluid. Preferably the supercritical fluid is carbon dioxide. Other embodiments of the invention include a nanoweb composite provided by the method.
