摘要：

The effect of the cross-section of crystals and thickness of the amorphous phase in fibre-forming oriented polymers on transfer chains, kinks, and cilia" in them for different values of the forces that stretch the macromolecules in crystallization was investigated by the Monte Carlo method. It was found that the fractions of transfer chains and kinds in the polymer increase and the proportion of "cilia" decrease with an increase in the cross-section of the crystals. The increase in stretching of the macromolecules in crystallization increases the proportion of transfer chains and decreases the proportion of kinks. The average number of segments in the kink and transfer chain decreases with an increase in stretching of the macromolecules. The increase in the thickness of the amorphous region between crystals along the direction of the axes of the molecules in the crystals causes an increase in the proportion of kinks and a decrease in the proportion of transfer chains."
