In the late 1920s Bayer Company began reevaluating the emulsion polymerisation process of polybutadiene as an improvement over their Buna technology, which was based on sodium as a catalyst. Incorporation of styrene (qv) as a comonomer produced a superior polymer compared to polybutadiene. The product Buna S was the precursor of the single largest-volume polymer produced in the 1990s, emulsion styrene—butadiene mbber... 

The Delta Mooney (A Mooney) test is an extension of the Mooney used on empirical grounds as a general indication of processibility for non-pigmented oil extended emulsion styrene/butadiene rubber. It quantifies the changes that occur in Mooney viscosity with time, either as the difference between viscosities recorded at two specified times or as the difference between the minimum viscosity recorded immediately after the commencement of the test and the subsequent maximum viscosity. Several alternative Delta Mooney values are defined depending on the times, whether minimum/maximum viscosity difference is used and whether or not the sample has been massed on a mill. Procedures for Delta Mooney are standardised in ISO 289-341, BS 903 Part A58-142 and in ASTM D334643.

Wang and co-workers [6] used a Py-GC technique for the qualitative analysis of fumaric acid and itaconic acid as low-level monomers polymerised with other major monomers in emulsion styrene maleic anhydride co-polymers. In order for fumaric acid and itaconic acid to be detected through pyrolysis, the acids are derivatised with primary amines such as methylamine and ethylamine to form a cyclic imide. The detection of derivatised fumaric acid and itaconic acid was accomplished by atomic emission detection. The structures of the derivatisation-pyrolysis products were elucidated by MS.

Powdered rubber based on E-SBR/carbon black compoimded in an internal mixer process is examined with respect to the advantages it affords in terms of enviromnental, handling and efficiency over conventional bale technology. This paper is the first part of a series of publications which discusses the individual rabber/filler systems in detail, and focuses on the system of carbon black-filled emulsion styrene butadiene rubber. It covers the selection of the raw materials, manufacture of products and their characterisation. 18 refs.
