Abstract

Hydroxyethyl cellulose (HEC) grafting poly(caprolactone) (PCL) copolymer (HEC-g-PCL) was successfully synthesized by the protective technology of trimethylsilyl group. The poly(caprolactone) was grafted onto hydroxyethyl cellulose after the partial hydroxyl groups were firstly protected with trimethylsilyl group, then protective trimethylsilyl groups were taken off and the new graft copolymer was generated. The product was characterized by 13C NMR, the thermal properties analysis was also tracked with quadrate hyperthermic treatment. The results of the structure analysis indicated that poly(caprolactone) was connected to hydroxyethyl cellulose by chemical bond and the test showed that the thermal stability was changed along with the modified structure.
