Photopolymerizable compositions based on monomeric acryflc or other ethylenicaHy unsaturated acid derivatives are becoming increasingly popular. When multiftmctional derivatives are employed, three-dimensional networks having high strength and abrasion resistance are possible on exposure to light. A typical composition may contain an ethoxylated trimethylolpropane triacrylate monomer, a perester phenacjhdene initiator (69), and an acryflc acid—alkyl methacrylate copolymer as binder. 

A reactor containing acrylic acid (305 g), 37.3wt % aqueous sodium acrylate (3204 g), and water (1465g) was treated with ethoxylated (15 EO) trimethylolpropane triacrylate (12.2g), 2,2 -azobisamidinopropane dihydrochloride (0.61 g), and sodium persulfate (3.05 g). The mixture was purged for 30 minutes and further treated with hydrogen peroxide (0.244 g) dissolved in water (5g) and ascorbic acid (0.244 g) also dissolved in water (5g). The mixture was then heated in a thermally insulated mb for about 30 minutes the temperature at the start of the reaction was 113 C. The reaction started after a few minutes and proceeded under adiabatic conditions until the product was isolated and comminuted through a meat grinder equipped with a 6 mm breaker plate. The residue was dried at 80°C under reduced pressure and the produce, was isolated having a sieve fraction of 300 to 600 pm.

Cure enhancers for UV/EB and peroxide-cure systems are low-volatility liquid monomer SR-502 ethoxylated trimethylolpropane triacylate, curing rapidly in systems to increase flexibility, weather resistance, chemical resistance, shrinkage, abrasion resistance, and impact strength, for coatings, PVC flooring, and photopolymers and CD-501 propoxylated trimethylolpropane triacrylate, for low shrinkage in acrylics, adhesives, coatings, electronics, and photopolymers.
