A Textbook of Manufacturing Technology: Manufacturing Processes
Comparison between Addition and Condensation Polymerisation
Depolymerisation may also take place in plastics formed at high temperature due
to thermal vibrations which may disrupt the inter-molecular bonds within the
molecules.

Synthetics, Mineral Oils, and Bio-Based Lubricants: ...
Under conditions of rapid depolymerisation it has been shown that the main
product of decomposition is isobutylene. Depolymerisation of the polymer chain
does not proceed rapidly below temperatures of 180 to 200°C. At these
temperatures, ...

Thermal Degradation of Polymeric Materials
After formation of a polymeric radical, depolymerisation occurs for PMMA to form
MMA monomer. Random chain scission occurs above 300 °C, leading to
depolymerisation and monomer volatilisation {443515}. PMMA degrades
predominantly ...

Properties and Applications of Elastomeric Polysulfides
The effect of depolymerisation will be greater when three depolymerisation
processes, instead of two, bare completed with the same total amount of sodium
hydrogen sulphide and sodium sulphite. When depolymerisation is repeated, the
...
Oxidative-reductive Depolymerisation of Alginate, Hyaluronate, and Other
Polysaccharides In the ascorbic acid-induced depolymerisation of hyaluronic
acid, as measured by viscometry, degradation of diketogulonic acid was one of
the major ...

Carbohydrate Chemistry: Chemical and Biological Approaches
Anionic oligosaccharides are classically obtained by two different ways: by de
novo chemical synthesis (often from monosaccharides) or by partial
depolymerisation of polysaccharide in controlled conditions. Two
depolymerisation methods ...
