It was first produced by Bernard Redfern in the mid-1950s at the laboratories of The Carborundum Company, Manchester, UK. He had set out to develop a polymer matrix to mirror a diamond structure and discovered a resole (phenolic) resin that would, with special preparation, set without a catalyst.

Who invented allotropes?

The term allotrope was first suggested by Swedish chemist Jöns J. Berzelius (1779–1848) when he questioned whether a given element could exist in two or more forms with different chemical and physical properties.

Why allotropes are formed?

Enantiotropic allotropes have several forms, each of which is stable under different sets of conditions. It is possible to convert one form into another form by change these conditions (such as temperature and pressure). The elements carbon, oxygen, sulfur, tin and phosphorus all have allotropic forms.
