Procedure

Then, after adding a mixture of 17.2 g of acrylic acid and 150 g of toluene to the reaction mixture obtained above together with 1.0 g of t-butylhydroquinone, the reaction was further carried out under refluxing with stirring for 4 hours. After cooling to room temperature, the reaction mixture obtained was reprecipitated from 2 liters of methanol and the solid thus precipitated was collected by filtration and dried under reduced pressure to obtain 135 g of Macromonomer MM-1 having a weight average molecular weight of 6.8×103. ##STR51##
