Abstract
Provided are a thermoplastic polyurethane foam and an impact resistant composite laminate. The thermoplastic polyurethane comprises a structural unit represented by Formula (I): wherein each R independently is an alkylene group having 2 to 8 carbon atoms or —CH2CH2OCH2CH2— or —CH2CH2OCH2CH2OCH2CH2—; n is a number from 2 to 13; and the structural unit has a Mn ranging from 700 g/mole to 2500 g/mole. The impact resistant composite laminate comprises a base layer and a first impact resistant layer formed by the thermoplastic polyurethane foam, and the first impact resistant layer overlaps the base layer.
