Thioxanthone-benzotriazole: Initiator and stabilizer properties in one component

The initiation efficiency of 3H-5-Thia-1,2,3-triaza-cyclopenta[b]anthracene-10-one (TX-BT) for free radical polymerization of methyl methacrylate (MMA), is enhanced by the addition of N-methyldiethanolamine (MDEA) to the initiator formulation. Photodegradation of polymethylmethacrylate (PMMA), which...

Description
Summary:The initiation efficiency of 3H-5-Thia-1,2,3-triaza-cyclopenta[b]anthracene-10-one (TX-BT) for free radical polymerization of methyl methacrylate (MMA), is enhanced by the addition of N-methyldiethanolamine (MDEA) to the initiator formulation. Photodegradation of polymethylmethacrylate (PMMA), which was prepared with and without TX-BT, was examined according to its weight loss. The beneficial effects of TX-BT as initiator and stabilizer for polymerization of methyl methacrylate was determined.
