描述了固相合成结构确定的聚氨酯低聚物和共聚物所需的一系列双官能甲硅烷氧基甲基异氰酸酯单体的合成。因此，MDI模拟物2、3是通过二对甲苯基甲酮和叔丁基二苯基甲硅烷氧基甲基芳基异氰酸酯19、22和叔丁基二苯基甲硅烷氧基乙氧基乙基异氰酸酯25（一种脂肪族变体）的去对称序列合成的，它们都是由市售氨基醇合成的。
The synthesis of a series of bifunctional siloxymethyl isocyanate monomers, required for the solid phase synthesis of structurally defined polyurethane oligomers and copolymers is described. Thus, the MDI mimics 2, 3 were synthesised via a desymmetrisation sequence from di-p-tolylmethanone and the tert-butyld iphenylsiloxymethylaryl isocyanates 19, 22 and tert-butyldiphenylsiloxyethoxyethyl isocyanate 25, an aliphatic variant, which were all synthesised from commercially available amino alcohols.
