THE DEVELOPMENTS SERIESDevelopments in many fields of science and technology occur at such a pace that frequently there is a long delay before information about them becomes available and usually it is inconveniently scattered among several journals.Developments Series books overcome these disadvantages by bringing together within one cover papers dealing with the latest trends and developments in a specific field of study and publishing them within six months of their being written.Many subjects are covered by the series, including food science and technology, polymer science, civil and public health engineering, pressure vessels, composite materials, concrete, building science, petroleum technology, geology, etc.Information on other titles in the series will gladly be sent on application to the publisher.

It should be read in conjunction with Developments in Rubber Technology-l as that volume discussed developments in natural rubber and selected special purpose synthetic rubbers as well as additives.The authors have been selected for their expertise in each particular field and we, as editors, would like to express our appreciation to the individual authors and also to their companies. Such a book would be impossible to produce without such active cooperation as we have received.Volumes 1 and 2 of Developments in Rubber Technology cover rubbers which are processed and vulcanised in the traditional manner. It is appreciated that the omission of non-vulcanised rubber materials (the socalled thermoplastic elastomers) will be unwelcome to many readers but it is intended, because of the size of the subject, to cover these materials in a subsequent volume. v A.W.

Copolymerization of polar vinyl monomers with butadiene in the presence of Lewis acids

et al. 1976

The copolymerization of acrylonitrile (AN), methacrylonitrile (MAN), methyl acrylate (MA), and methyl methacrylate (MMA) with butadiene (BD) in the presence of ethylaluminium dichloride, zinc chloride, and stannic chloride was investigated. The reactivity of polar monomers in the copolymerization was found to decrease in the following order: AN>MAN>MMA>MA. It was also found that AN and MAN form with BD copolymers of essentially 1 : 1 composition; MMA, and particularly MA were found, however, to form with BD copolymers of a composition different from 1 : I.In competition with the copolymerization, a Diels-Alder reaction was shown to occur in the investigated systems. The reactivity of polar monomers in the Diels-Alder reaction was found to increase in the following order: MAN < AN < MMA < MA. In the presence

Alternating copolymerization of acrylonitrile with butadiene in the presence of binary and ternary catalytic systems of Lewis acids type

Acrylonitrile (AN) and butadiene (BD) were copolymerized in the presence of binary C2H5AICI2-MtX, (MtX, =metal halide or metal alkoxide) and ternary ZnCI2-R,MtX,-VOCI3 (R,MtX, =metal alkyl or alkylmetal chloride) catalytic systems. The yield of the copolymer (mole ratio of units AN/BD = 1 : 1) formed in the presence of the above systems, and the effects of the molar proportion of catalyst components, of the reaction temperature and time on the copolymer yield in some systems were determined. The role of individual components of binary and ternary catalytic systems in the copolymerization is discussed.
