Abstract:
A process for the preparation of barium containing polyacrylates for optical and coating applications. The process consists in dispersing octahydrate of barium hydroxide in acrylic acid to form a monomer mixture. An aromatic carboxylic acid is added to the monomer mixture and then a cross linking agent is added thereto. Such a monomer mixture is subjected to the step of polymerization by gamma radiation.
