Description
| - The work directs attention towards the influence of annealing temperature on polymorphic transformation in isotactic polybutene-1 (PB-1). Polybutene-1 crystallizes from melt into the unstable form II. Depending on temperature and pressure conditions PB-1 recrystallizes into stable form I upon thermal ageing. For the purposes of present work, three different polybutene-1 materials, two homopolymers and ethylene-copolymer were processed using injection moulding to prepare samples for further analyses. These were characterized by tensile testing. Then, the samples were annealed at five different temperatures in time interval from 0 up to 48 days at ambient pressure. It has been observed that temperature directly influences the transformation rate from form II into form I.

- Práce je zaměřena na vliv temperační teploty na transformaci izotaktického polybutenu-1 (PB-1). PB-1 krystalizuje z taveniny do nestabilní fáze II. V průběhu času PB-1 rekrystalizuje do stabilní fáze I a to v závislosti na teplotě a tlaku. V této práci byly použity 2 homopolymery a 1 etylén-kopolymer. Vzorky byly připraveny vstřikováním a následně temperovány při 5 různých teplotách 0 až 48 dní. Byl pozorován vliv teploty na rychlost transformace. (cs)
