摘要

Abstract

Low density polyethylene film surface-grafted resorcinol was prepared by a sequential process.Firstly

acrylic acid was grafted to the surface of low density polyethylene by UV photo-grafting.Secondly

the carboxylic groups in poly(acrylic acid) chains were transferred to acyl chloride groups by the reaction of carboxylic groups with thionyl chloride.The stability of acyl chloride groups in several solvents(alcohol

water

acetone

aqueous NaOH and in N2 atmosphere) was investigated

and N2 atmosphere and acetone were appropriate media to protect acyl chloride groups from side reaction.Finally

resorcinol monomer reacted with acyl chloride to append to the poly(acrylic acid)chains at room temperature.FT-IR-ATR was used to characterize the change of carbonyl groups during each step of the grafting process.Furthermore

by the experimental data of gravimetric analysis the grafted resorcinol monomer on the surface of low density polyethylene film was verified to have undergone condensation with acetone further in the resorcinol/acetone solution at 56℃

which might be a useful feature for synthesizing a thermoplastic/thermosetting composition.
