制备了三种芳香族聚酰胺(PAs),其中一种包含具有新的具有庞大的侧链极性基团的芳香族二胺单体的二甲基二苯基硅烷单元。所有PA均以高收率获得,并且固有粘度在0.30至0.47dL g -1的范围内。所得的聚酰胺在各种非质子极性有机溶剂中显示出优异的溶解性。PAs具有300-371°C的热分解温度(TDT 10%)和玻璃化转变温度(T g)值较高(215至250°C)的热稳定性。功率放大器每摩尔重复单元中主链中含有硅原子的水的摩尔数最高。为了了解聚合物膜的亲水性,还测试了接触角。
Poly(esters) with two Si atoms in the main chain showed higher values of Tg than those with two Ge atoms, and the same was observed for poly(esters) with phenyl groups bonded to the heteroatoms, instead of those with methyl groups. Thermaldecomposition temperatures were also higher for those poly(esters) with two Si atoms in the main chain and those in which the heteroatom is bonded to phenyl groups
摘要 衍生自酰氯双(4-氯甲酰基-苯基)-二甲基-硅烷、双(4-氯甲酰基-苯基)-二甲基-锗烷的主链含Si和/或Ge的聚(酯)的热性能,双(4-氯甲酰基-苯基)-二苯基-硅烷和双(4-氯甲酰基-苯基)-二苯基-硅烷,以及双酚双(4-羟基苯基)-二甲基-硅烷、双(4-羟基苯基)-二甲基-锗烷通过差示扫描量热法和动态热重法研究了双(4-羟基苯基)-二苯基-硅烷和双(4-羟基苯基)-二苯基-锗烷。在主链中具有两个 Si 原子的聚(酯)比具有两个 Ge 原子的聚(酯)显示出更高的 Tg 值,并且观察到具有与杂原子键合的苯基而不是具有甲基的聚(酯)的聚(酯)的 Tg 值。

Three aromatic poly(amides) (PAs) were prepared, one of them containing a dimethyldiphenylsilane unit from a new aromatic diamine monomer with a bulky pendant polar group. All PAs were obtained in high yield and the inherent viscosities were in the range of 0.30 and 0.47 dL g−1. The obtained poly(amides) showed excellent solubility in a variety of aprotic polar organic solvents. PAs evidence thermal
