| Popis: | A greatly improved and very reliable synthesis of head to head polystyrene (HHPS) was worked out. HHPS was prepared in a sequence of four steps starting with a reductive photodimerization of acetophenone. The resultant 2,3-diphenyl-2,3-butanediol was dehydrated in vacuum to 2,3-diphenyl-1,3-butadiene, which was polymerized to 1,4-poly(2,3-diphenyl-1,3-butadiene) (PDPBD). PDPBD was then hydrogenated (reduced) with potassium and ethanol to HHPS. |
