Claims
- 1. A liquid poly(thioether ether) prepared by reacting, under free-radical conditions, diallyl ether with at least two different dithiols selected from the group consisting of 1,2-ethanedithiol, 1,3-propanedithiol, 1,4-butanedithiol, and 1,6-hexanedithiol.
- 2. The poly(thioether ether) of claim 1 having a DSC melting point less than about 0.degree. C.
- 3. The poly(thioether ether) of claim 1 having a number average molecular weight within the range of about 200 to about 5000.
- 4. A hydroxy-terminated poly(thioether ether) prepared by reacting, under free-radical conditions, the liquid poly(thioether ether) of claim 1 with allyl alcohol to produce a hydroxy-terminated poly(thioether ether).
- 5. A poly(thioether ether) prepared by reacting, under free-radical conditions, diallyl ether with a dithiol selected from the group consisting of 1,2-ethanedithiol, 1,3-propanedithiol, and 1,4-butanedithiol.
- 6. The poly(thioether ether) of claim 5 having a number average molecular weight within the range of about 200 to about 5000.

- 8. A hydroxy-terminated poly(thioether ether) prepared by reacting, under free-radical conditions, the poly(thioether ether) of claim 5 with allyl alcohol to produce a hydroxy-terminated poly(thioether ether).
- 9. The hydroxy-terminated poly(thioether ether) of claim 8 having the formula:
