The cyclopolymerization of 3,4-di-O-allyl-1,2 : 5,6-dianhydro-D-mannitol ( 1) was carried out using BF 3 rOEt 2 and t-BuOK. The polymer obtained by the polymerization with BF 3 rOEt 2 mainly consisted of (1r6)-bonded 3,4-di-O-allyl-2,5-anhydro-Dglucitol as the five-membered constitutional repeating
