| Abstract: | A new type of unsaturated polyester resin was synthesized with tolulene diisocyanate modified method.The resin could be cured at ambient temperature and the tensile strength and elongation at break of the cured resin were 20 MPa and 106% respectively,which could be used to make high flexible products or could be also added in normal unsaturated polyester resins to improve their anti-impact properties and elongation at break. |

| Keywords: | unsaturated polyester tolulene diisocyanate polyurethane elongation at break tensile strength |
