## Abstract The photodegradation of thin films of poly‐α‐methylstyrene by near ultraviolet radiation has been studied in vacuum at 27 and 115°C. Changes taking place during photolysis were followed by a determination of monomer formation by ultraviolet spectroscopy, residue molecular weight through
## Abstract Block copolymers were synthesized by the condensation of dihydroxyl‐terminated poly‐(α‐methylstyrene) oligomers and bisdimethylamino‐terminated poly(dimethylsiloxane) oligomers. Manipulation of block molecular weight produced copolymers ranging in composition from 21% to 73% poly(dimeth
