发明名称	Thermoplastic Polyurethane Foamed Articles Comprising A Thermoplastic Polyurethane Composition And An Epoxy, Functional Styrene Acrylic Copolymer
摘要	A thermoplastic polyurethane foamed article has a plurality of bubbles distributed throughout the thermoplastic polyurethane foamed article and comprises a thermoplastic polyurethane composition and an epoxy-functional styrene acrylic copolymer which are foamed in the presence of a blowing agent. The epoxy-functional styrene acrylic copolymer is present in an amount ranging from 0.1 to 5% of the total combined weight of the thermoplastic polyurethane composition and the epoxy-functional styrene acrylic copolymer. The thermoplastic polyurethane foamed article has an average diameter of the plurality of bubbles ranging from 50 to 120 μm with at least 75% of the plurality of bubbles having a diameter of less than 200 μm.
