A Markoff chain model for crystalline polymers

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

A molecular model for completely unoriented polymer chains which can be formed on a square lattice is presented. Using the mathematical methods of the Markoff formalism, expressions for the dimensions of the molecular chain, values for the per cent crystallinity and sequence length in amorphous and crystalline regions are derived in terms of two probability parameters. The problem of excluded volume is not considered.

Riassunto

Si presenta un modello molecolare per catene di polimeri completamente prive di orientazione che possono essere disposte su un reticolo quadrato. Servendosi dei metodi matematici del formalismo di Markoff, si deducono le espressioni delle dimensioni della catena molecolare, i yalori della cristallizzazione peroentuale e la lunghezza della successione nelle regioni amorfe e cristalline, in funzione di due parametri di probabilità. Non. si considera il problema del volume escluso.
