| Abstract: |
| The expoxidized SBS was prepared by the reaction of the toluene and cyclohex anesolution of SBS with the peroxy acetic acid which was made in situ with acetic acid and hydrogen peroxide.The effect of the mass fraction of epoxy groups on the properties of epoxidized SBS was investigated.The results showed that the molecular weight of epoxidized SBS changed little when its mass fraction of epoxy groups was in the range of 0～0.06；the tensile strength，modulus at 300% elongation，elongation at break and permanent set at break decreased slightly and the oil resistance and adhesion strength improved as the mass fraction of epoxy groups increased. |
