Importance of Boscovich's theory of natural philosophy for polymer science ∗)

Summary — It has been generally accepted that the macromolecular hypothesis was for the first time presented by H. Staudinger (1920). It is shown in this article, however, that Roger Boscovich, in his monumental work “Theory of natural philosophy”, as early as in the 18th century, pointed out that the spiral atomic chains could be formed. He also pointed that the shape of the chain could be markedly changed due to slight changes of the distances among the atoms. The elastic properties of the chains have been stressed. The author of this article also presented some examples of the applications of Boscovich‘s theory for the interpretation of free-radical polymerization of compressed ethylene gas and liquid methyl methacrylate. The priority of Boscovich‘s macromolecular hypothesis is doubtless
