21. It is created by 1, 4 topochemical polymerization of diiodobutadiyne. 22. It undergoes rapid polymerization , including forming a hemiacetal cyclic dimer. 23. These special drying oils undergo a process known as polymerization . 24. He also invented techniques for forming precision lenses and prisms through polymerization . 25. The polymerization of acetylene with Ziegler-Natta catalysts produces polyacetylene films. 26. This allows the possibility of both types of polymerization mechanism. 27. Storing cyanoacrylates below will nearly stop the polymerization process and prevent aging. 28. Alternatively, the polymerization is conducted using a surfactant such as PFOS. 29. In different minerals the tetrahedra show different degrees of networking and polymerization . 30. Fibrin polymerization disorders can be detected by viscoelastic methods such as thrombelastometry.
