Beschreibung
Zusammenfassung:	FIELD: polymer materials. SUBSTANCE: polymer composition including polyester block copolymer with elastic and rigid blocks and polybutadiene-based block copolymer is distinguished by that polyester block copolymer (40-95%) is composed of elastic blocks on the basis of polytetramethylene oxide with molecular weight 1000-5000 (40-60%) and of rigid blocks on the basis of polytetramethylene terephthalate with molecular weight 1100-1500 (60-40%), polybutadiene-based block copolymer (5-60%) is butadiene-alpha-methylstyrene block copolymer composed of poly-alpha-methylstyrene blocks with molecular weight 6000-20000 (30-50%) and polybutadiene blocks with molecular weight 20000-60000 (50-70%), and composition additionally contains pigment (0.1-2.0%). EFFECT: improved frost and heat resistance. 2 tbl, 6 ex
