Abstract
Official abstract text for this publication.
Polymeric blends having improved flame retardance properties and good ductility at low temperatures are disclosed. The blend is formed from (A) a photoactive additive containing a photoactive group derived from a monofunctional benzophenone; and (B) a polymer resin which is different from the photoactive additive. The additive can be a compound, oligomer, or polymer. When exposed to ultraviolet light, crosslinking will occur between the photoactive additive and the polymer resin, enhancing the chemical resistance and flame retardance while maintaining ductility.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polymeric blend, comprising: a photoactive additive containing a photoactive group derived from a monofunctional benzophenone; and a polymer resin which is different from the photoactive additive; wherein the photoactive additive is a cross-linkable polycarbonate resin having the structure of Formula (I): wherein R 1 and R 2 are ind…
