Abstract
The new conception of the polymeric-polymorphoid structure of glass and glassforming
liquid of individual chemical substances (ICS) is presented. The analysis of numerous data of X-ray
diffractometry, DSC, Raman spectroscopy etc. shows that such glassforming ICS as SiO2, GeO2.
H2O, Se, GeS2, GeSe2, As2S3, AsSe, BeCl2 and other are the copolymers of the structural fragments
(polymorphoids) having no translation symmetry of two (or more) polymorphous modifications
(PM) of these substances. The physicochemical essence of glass transition process is discussed.
