[交流] 【求助】求翻译聚合物术语 已有1人参与

小虫不是高分子专业,看一篇聚合物方面文献,N多术语不知,求大侠解惑

1。Their polycondensations were carried out in bulk at 140–160 ◦C without catalyst
请问这句话里的in bulk该如何翻译?

2。With the first, irradiation at 350nm had to be done on the spin-coated film (not in solution) for 10–20 min in order to be irreversible. The cross-linking proceeded by cycloaddition and the film produced was insoluble. The polymers obtained with the second photoreactive monomer formed the Grandjean texture only at high temperature (>250 ◦C) and its photocuring was not presented.
求这一整段的准确翻译!

先谢过!!
