Copolymer hydrogenation

We consider an incompressible (m-l-1) multicomponent mixture of polymers consisting of m different types of polymer chains within a matrix referred to as 0 . Components may be either homopolymers of a given chemical species or, e.g. homopolymer sections in block copolymers. Hydrogenated and deuterated species of the same homopolymer are considered as different components. In this context a diblock copolymer is a two-component polymer system. A mixture of partially protonated diblock chains hA-dB with deuterated diblock chains is consequently regarded as a four-component system. [Pg.163]

During radiolysis of polybutadiene and butadiene-styrene copolymers hydrogen and methane evolve. The incorporation of styrene as comonomer strongly reduces the total gas yield. Small amounts (typically 2 phr) of N-phenyl- 3-naphtylamine greatly reduce the gas yield and at the same time reduce G(X) considerably. [Pg.108]

As the amount of polar units in the backbone architecture is increased, copolymer-copolymer polar interactions increase and high temperatures are required to dissolve the copolymer in nonpolar solvents. If the copolymer has a comonomer capable of hydrogen bonding, the solubility in alkane and alkene solvents is dramatically reduced at lower temperatures, where copolymer-copolymer hydrogen bonding is much stronger than other intermolecular interactions. The solubility of copolymers greatly increases in the solvents that... [Pg.15]

Most of styrene-butadiene copolymers hydrogenation studies have focused on global saturation of polybutadiene double bonds (i.e. 1,4-trans, 1,4-ds and 1,2-vinyl) and on obtaining high saturation percentages (>90%), however, only a few of them have made a distinction on the saturation of the different types of double bonds present in polybutadiene (Escobar et al., 2000). [Pg.206]

These catalysts were used for random ester-carbonate bulk copolymerizations. Furthermore, by combining sequential polymerization techniques using bifunctional initiators, the mild polymerization conditions allow for the preparation of block copolymers. Hydrogen bond activation of monomer and initiator/propagating species was proposed as the underlying mechanism, which can be tuned to mitigate adverse side reactions (Scheme 36). [Pg.267]
