Synthesis and properties of cis‐and trans‐methoxyvinyl chloride (MVC) are described.Both of these monomers can be polymerized with cationic initiators. From the 13 C‐NMR spectra it was concluded, that poly‐(trans‐MVC) is mainly threo‐diisotactic. Copolymerization of cis‐MVC with for instance trans‐MVC or styrene or 1,3‐dioxolane is also described. The ring‐opening polymerization of 2‐phenyl‐2‐oxazoline under different conditions was investigated.The molecular weights, determined by light‐scattering and GPC are in the range between 10 000 and 350 000. A[η] ‐M‐ equation was derived. By hydrolysis with hydrochlorid acid high molecular weight poly(iminoethylene) was obtained. The ring‐opening polymerization of 1‐azabicyclooctane [4.2.0] (conidine) with different catalysts as well as the properties of the polymers were studied in detail.By means of a “mixed‐mechanism technique” well defined styrene‐conidine diblock copolymers are available.
