Versuchsvorschrift

A mixture of 38.7% beta-pinene, 25.0% methyl acrylate, 30.7% hydroxypropyl acrylate, 0.8% acrylic acid and 4.8% di-t-butyl peroxide was continuously fed to a 5 gallon continuous stirred tank reactor at a rate calculated to give a average residence time of 20 minutes. The reactor was maintained at a pressure of 500 psig and a temperature of 365° F. The reaction product was continuously pumped to a 30 gallon flash tank maintained at 20% fill level together with di-t-amyl peroxide (4% by weight on reaction product). The contents of the flash tank were maintained at 300° F. The output from the flash tank was mixed with sufficient butyl acetate in a static mixer to reduce the solids content to 81% and drained into storage containers. The reaction was run for a period of 6.5 hours. The resulting resin had a weight average molecular weight of 5000.
