Reaction Steps

96.0 grams IEM was added to 77.0 grams (10% excess) caprolactam plus 0.17 grams dibutyltin dilaurate (DBTDL) under agitation at 75° C. over a period of 30 minutes, and held at 75° C. for a further 3 hours at which point the free NCO content had dropped to a trace by infrared spectroscopy. The product (IB) was a syrupy liquid.
