実験手順

Charge 1 was added to a 4-liter stirred stainless steel pressure reactor. The reactor was pressurized with nitrogen providing a 5 psig pad on the reactor. The agitation on the reactor was set at 500 rpm and the reactor temperature was adjusted to 150° C. Charge 2 was added to the reactor at an addition rate of 36 grams/hour over a 2.5 hour period. After 15 minutes Charge 3 was added to reactor at an addition rate of 1000 grams/hour over a 2 hour period. During the monomer addition the temperature was maintained at 150° C. and 60 PSI. After Charges 2 and 3 were in the reactor, the reaction mixture was held for 2 hours. The reactor was than cooled to 25° C. GC analysis of the reaction mixture showed that all acrylates and styrene were reacted. The final solids of the resulting polymer was 83.12% determined at 110° C. for one hour. The copolymer had Mn=1400 and Mw/Mn=2.4. The 13C NMR spectrum was consistent with a molar copolymer composition of 22.1% diusobutylene, 35.0% hydroxypropyl acrylate, 15.6% isobornyl-acrylate, 7.8% styrene, and 19.5% butyl acrylate.
