Abstract
A novel hydroxyl-terminated liquid fluoroelastomer (HTLF) was synthesized; FT-IR, GPC and 1H-NMR result show that HTLF was synthesized successfully. Then HTLF was cured with HDI trimer, the structure of cured product was characterized by FT-IR. Compared with traditional solid fluorine elastomer, Cured HTLF has higher char yield and faster thermal decomposition rate. It ascribed to the introduction of ring structure the cross-link structure formed in the curing process. The study of chemical resistant properties and tensile strength of cured fluoroelastomer film suggested that Cured HTLF was provided with similar mmechanical properties, chemical resistant property than solid fluorine elastomer.
