Teoreticno smo proucevali termodinamsko stanje raztopin mesanic
sintetiziranega termoplasticnega poliuretana (TPU) in kloriranega
termoplasticnega poliuretana (CTPU) s stiren/akrilonitrili (SAN)
z razlicnimi vsebnostmi akrilonitrila. Na osnovi modificirane
Flory-Hugginsove teorije raztopin smo izracunali interakcijski
parameter (#4 12 ) mesanic razlicnih sestav.

Kljucne besede: mesanice polimerov, termoplasticni poliuretan,
klorirani termoplasticni poliuretan, stiren/akrilonitril,
termodinamika, interakcijski parameter

Thermodynamics of polymer blends of synthesized thermoplastic
polyurethane (TPU) as well as chlorinated thermoplastic
polyurethane (CTPU) with styrene/acrylonitriles (SANs) with
different amount of acrylonitriles was investigated
theoretically. Based on the modified Flory-Huggins theory, the
interaction parameter (#4 12 ) of polymer blends of different  
compositions was calculated.

Key words: polymer blends, thermoplastic polyurethane,
chlorinated thermoplastic polyurethane, styrene/acrylonitrile,
thermodynamics, interaction parameter
