摘要：

Model urethane networks prepared from polyoxypropylene tetrols and hexamethylene diisocyanate have been studied with the aid of the computer. Good agreement with experiment is found for gel points when the crosslinkers are treated as sticks. The simulation-theory moduli for the phantom model show good agreement with experiments for networks prepared with Mn = 1200 in the bulk and at various dilutions, or with Mn = 2100 in the bulk. Simulations underestimate moduli for networks prepared from Mn = 2100 at various dilutions by factors of less than 2. © 1990.
