WATER BASED CONCENTRATED PRODUCT FORMS OF PHOTOINITIATORS MADE BY A HETEROPHASE POLYMERIZATION TECHNIQUE |
摘要 |
The invention relates to a concentrated aqueous polymer dispersion with an average particle size of less than 1000 nm comprising a) a polymer carrier prepared by heterophase radical polymerization of at least one ethylenically unsaturated monomer in the presence of b) a photoinitiator and/or photolatent catalyst and c) optionally a non-ionic, cationic or anionic surfactant, wherein the weight ratio of the photoinitiator and/or photolatent catalyst to the polymer carrier is greater than 20 parts of photoinitiator and/or photolatent catalyst per 100 parts of polymer carrier, preferably equal or greater than 35 parts of photoinitiator and/or photolatent catalyst per 100 parts of polymer carrier. |
