Cumulative Subject polymers

Allen, G. and J. C. Bevington (eds.), Comprehensive Polymer Science , Pergamon Press, Oxford, 1989. A series of volumes that show the relationship between methods of preparation, treatment, structure and properties. It is organized into seven volumes Volume 1, Polymer Characterization Volume 2, Polymer Properties Volumes 3 and 4, Chain Polymerization Volume 5, Step Polymerization Volume 6, Polymer Reactions Volume 7, Specialty Polymers and Polymer Processing. A cumulative subject index completes the final volume. 

When disks containing insulin dispersed in the polymer were subjected to well controlled low pH pulses and the cumulative amount of insulin released during each pulse determined by radioimmunoassay, the results shown in Fig. 20 were obtained. The progressive decrease with repeated stimulation represents a gradual depletion of insulin from the device.
