Cyclic Oligomers in the Cationic Polymerization of Heterocycles
The cationic polymerization of heterocyclic monomers may lead to polymers containing substantial, yet Variable amounts of cyclic oligomers. This review gives a survey of the systems where such oligomers have been found. Oligomer formation is generally observed in the polymerization of oxiranes and thiiranes. The most frequently observed oligomers are the cyclic dimers and cyclic tetramers but o...
متن کاملCoordination (co)polymerization of olefins
Introduction Middle 1950s may be treated as the beginning of the age of plastics – their global production in last 60 years have increased from approx. 1.5 mln to almost 290 mln tons. The dominating position in production and consumption of these materials for many years has been occupied by polyolefins (in Europe 48% from 57 mln tons of plastics) [1]. Forecasters predict that in coming years t...
متن کاملAqueous Catalytic Polymerization of Olefins
Aqueous catalytic polymerization may seem like a contradiction at first sight. The high water sensitivity of Ziegler or Phillips catalysts applied commercially for the production of polyolefins is well known. However, water offers a unique combination of properties as a medium for polymerization reactions: A high heat capacity, which enables an effective transfer of the heat of polymerization. ...
متن کاملLiving Cationic Polymerization of Olefins. How Did the Discovery Come About?
The tortuous road to living carbocationic polymerizations is chronicled. The impetus for this project was my conviction that, just as living anionic polymerizations have started with a critical insight, a similar breakthrough will also be possible with cations. Upon retrospect, the facts show a three-step progression to the objective: Discovery of 1) controlled initiation, 2) reversible termina...
