20140161856 | Retention of PBO in Polymer Matrices by Phthalocyanines - By incorporating PBO and phtalocyanine in a polymeric matrix, the surface concentration of the PBO after migration to the surface is reduced relatively to a matrix without phtalocyanine. This can be used to control the migration of PBO and retain PBO for a long-lasting effect. | 06-12-2014 |
