A series of polyurethane elastomers based on an aliphatic diisocyanate and a polyether macroglycol was polymerized with various cross-link densities and OH/NCO ratios. Stoichiometries yielding between 8,600 and 12,900 gm/mole/crosslink and an OH/NCO ratio of 1.1 resulted in polymers with the low modulus, yet high strength and elongation necessary for maxillofacial applications.
一系列基于脂肪族二异氰酸酯和聚醚大二醇的聚氨酯弹性体，以不同的交联密度和OH/NCO比率进行聚合。化学计量比在8600至12900克/摩尔/交联之间且OH/NCO比率为1.1时，得到的聚合物具有低模量，但具备颌面应用所需的高强度和高伸长率。
