Methyl­ and Isobutylaluminoxanes as Effective Modifiers for NdCl₃·3(i­С₃Н₇OН) – Аl(i­С₄Н₉)₃ Catalytic System – Akhmetov I.G., Vagizov A.M. (P. 2).

Isoprene polymerization under the influence of the NdCl₃·3(i­С₃Н₇OН)– Аl(i­С₄Н₉)₃ catalytic system modified with methyl­ and isobutylaluminoxane was studied. Kinetic polymerization parameters, molecular characteristics and polymer microstructure were defined. More effective activation of catalytic system by methylaluminoxane is assumed to be connected with minimal steric hindrance on coordination of the modifier nearby an active site.

Key words: polyisoprene, synthesis, catalytic system, modification, methyl­ and isobutylaluminoxane

Application of Destructed Synthetic Butadiene Rubber in the Synthesis of Polydicyclopentadiene – Bogomolova М.N., Zemlyakov D.I., Sidorenko N.I., Ashirov R.V., Rusakov D.A., Chaikovskii V.K. (P. 6).

Effect of destructed synthetic butadiene rubber, obtained as a result of chemical removing of insoluble residue from polymerization equipment, on the properties of polydicyclopentadiene (poly­DCPD) was studied. The use of such modifying additives results in decrease of hardness and the glass transition temperature and small increase of Izod impact strength of poly­DCPD.
