This survey informs on possible applications of thermofractography for polymer analysis. Its place within the known polymer analytical procedures is established and a detailed description of the apparatus required and the procedures are given. The essential characteristics of the new method are introduced in practical analytical examples and the predominant advantages underlined. Identifications of natural polymers, such as lignins, tannins, cellulose and proteins are described as well as those of plastics, such as phenol resins, epoxy resins and hardeners, polycondensates and vinyl polymers, also of plastic additives such as P VC plasticisers. In most cases, an identification scheme is given.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
