配制方法:

Add isophthalic and adipic acids to hot glycols and react to an acid number of 10-20. Cool prepolymer to 170'C or lower, add maleic anhydride, reheat and react to indicated final acid number and viscosity. Cool resin to 205'C, inhibit with 50 ppm hydroquinone and blend into styrene inhibited with 100 ppm p-benzoquinone.
