Toluene → Styrene p-methylstyrene

Participants

Reaction Conditions

Reaction Steps

To a glass bottle capped with a septum and flushed with nitrogen were added: 20 cc of purified toluene, 3.0 cc of purified styrene, 2.0 cc of purified p-methylstyrene, 2.8 mmol of TMA, 0.7 cc (1.412 mmol) of [(n-C4H9)3Sn]2O, and 0.0045 mmol of C5H5TiCl3. The mixture was stirred by a magnet stirrer for 22 h at 25° C. Then the content of the bottle was mixed with excess of isopropanol and 0.66 g of amorphous styrene-p-methylstyrene copolymer (yield ca. 14%) was recovered by filtration. The copolymer had a softening point of 122° C.
