Reaction Conditions

Reaction Steps

Charge 1 was added to a 4-liter stirred stainless steel pressure reactor. The reactor was then 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 addition rate of 18.00 grams/hour over 2.5 hours. After 15 minutes Charge 3 was added to reactor at an addition rate of 750.00 grams/hour over 2 hours. During the monomer addition the temperature was maintained at 150° C. at 70 PSI. After charge 2 and charge 3 were in the reactor, the reaction mixture was held for 2 hours. The reactor was then cooled to 25° C., and vented. GC analysis of the reaction mixture showed that all acrylates were reacted. The final solids of the resulting polymer were determined to be 76.46% at 110° C. for one hour. The copolymer had Mn=2090 and Mw/Mn=1.9. The 13C NMR spectrum is consistent with a molar copolymer composition of 30% hydroxypropyl acrylate, and 70% butyl acrylate.
