    Overture

    The development of the subject is traced from its origins in the discovery of ring-opening polymerization of cycloalkenes and the disproportionation of olefins, via the demonstration of double bond cleavage to...

    Tacticity in Polymers Initiated by Metathesis Polymerization: Effect of Catalyst

    Tacticity is defined in relation to ring opening metathesis polymerization and some predictions about tacticity are made on the basis of a mechamsm in which the propagating metal-carbene complex has a chiral m...

    The Metathesis Polymerization of Norbornene and Its Derivatives Initiated By Tungsten-Carbene Complexes: Relative Stability of the Intermediate Tungstenacyclo-Butane Complexes

    The early stages of the metathesis polymerization of norbomene and some of its endo derivatives, initiated by tungsten-carbene complexes of the type W(CR1R2)(OR3)2Br2.GaBr3, were followed in CD2Cl2 at 200–260 K b...

    Reaction of Nitrates with Liquid Sulphur Dioxide

    IT has been known for some time that inorganic nitrates catalyse the formation of polysulphones from liquid mixtures of olefines and sulphur dioxide1, but the mechanism of catalysis has never been clarified. It i...

    Reversibility of the Propagation Reaction in Polymerization Processes and its Manifestation in the Phenomenon of a ‘Ceiling Temperature'

    ALL addition polymerizations are exothermic and involve a decrease in entropy. The heat of reaction (q = ΔH) and the decrease in entropy (—ΔS) per mole of monomer polymerized really refer to the values of these q...
