We previously reported that cyclohexene and bicyclo[4.2.0]oct-1(8)-ene-8-carboxamides undergo efficient ruthenium-catalyzed alternating ring-opening metathesis polymerization (AROMP). Here, we demonstrate that cyclodecene and cyclododecene also function as cycloalkene monomers in the bicyclo[4.2.0]oct-1(8)-ene-8-carboxamide AROMP system, thus enabling the synthesis of linear alternating copolymers with spacers of different lengths, as demonstrated by means of NMR spectroscopy and gel permeation chromatography. The glass transition temperature and hydrophilicity of the alternating copolymers decrease as the length of the spacers increases, as determined by differential scanning calorimetry and water contact angle measurements.

将大环烯环引入交替共聚物中可以控制玻璃化转变和疏水性。


我们之前报道过环己烯和双环[4.2.0]oct-1(8)-ene-8-甲酰胺可以进行高效的钌催化交替开环复分解聚合（AROMP）。在这里，我们证明环癸烯和环十二烯也在双环[4.2.0]oct-1(8)-ene-8-carboxamide AROMP体系中充当环烯单体，从而能够合成具有不同长度间隔基的线性交替共聚物，如通过核磁共振波谱法和凝胶渗透色谱法所证明的。通过差示扫描量热法和水接触角测量确定，交替共聚物的玻璃化转变温度和亲水性随着间隔基长度的增加而降低。
