Reaction Steps

In a second step, a 3-necked reaction flask equipped with a thermometer, Dean Stark condenser, mechanical stirrer, heating mantle and nitrogen inlet, was charged with 60.7 g of the iBMA oligomer solution as prepared above (30 meq.), 8.1 g isostearylacohol (30 meq.) and 138.4 g MIBK. 50 g MIBK/H2O azeotrope was distilled off via the Dean Stark condenser. After replacing the Dean Stark by a normal reflux condenser, the mixture was cooled to 65° C. and 30.3 g MDI (240 meq.) were added. The reaction mixture was heated for 2 hours at 75° C.
