Abstract The photoswitchable poly(methyl methacrylate-random-methacrylate spirooxazine) was synthesized via atom transfer radical polymerization with the feed mole ratio of MMA/MSp comonomer of about 5. 5/1. Well-defined poly(methyl methacrylate- random-methacrylate spirooxazine) have been obtained with the average molecular weight (Mn) of 6500 g/mol and polydispersity of 1. https://www.spidertattooz.com/OPI-Nail-Lacquer-Do-You-Sea-What-I-Sea-0-5-oz-NLF84-p27741/
