Abstract
3-Methoxy-4-cyano-2, 9-dioxabicyclo[4.3.0]non-3-ene (1) was prepared by (4+2) cycloaddition reaction of methyl α-cyanoacrylate with 2, 3-dihydrofuran. Compound 1 was copolymerized with styrene by cationic initiator to obtain vinyl terpolymers containing 2, 3-tetrahydrofurandiyl group. Terpolymers 2 were soluble in common solvents and the inherent viscosities were in the range 0.2∼0.4 dL/g. Solution-cast films were clear and brittle, showing Tg value of 99.6℃.

Methyl α-cyanoacrylate를 2,3-dihydrofuran과 (4+2) 고리 부가반응시켜서 3-methoxy-4- cyano-2, 9-dioxabicyclo[4.3.0]non-3-ene (1)를 합성하였다. 2,3-Tetrahydrofurandiy]기를 포함하는 비닐 삼원공중합체를 합성하기 위해서 화합물 1을 스틸렌과 양이온 공중합시켰다. 삼원 공중합체 2는 상용 용매에 녹았으며 고유점도는 0.2∼0.4 dL/g을 나타냈다. 용액으로부터 만들어진 중합체 필름은 투명하고 취약성을 보였으며, 유리전이 온도는 99.6℃였다.
