For example, it was demonstrated that the copolymerization of (R)-β-butyrolactone and (S)-4-ethoxymethyl-2-propiolactone led to the formation of polymers with almost perfect alternating sequences ...

Copolymerization of 1,3-dioxolane(DOL) and isoprene(Ip) by BF 3 ·Et 2 O has been studied, particularly laying stress on the microstructure of the products. The diad fractions determined by NMR ...
