Abstract:
Urethane-urea-acrylic cast sheet materials are made from a reaction product of components including polyisocyanate compound having at least two isocyanate functional groups and optional polyol (or pre-reacted urethane prepolymer having at least two isocyanate functional groups), curative having at least two amine functional groups, acrylic monomer, and optional multifunctional monomer having a first functional group having an active hydrogen and a second functional group having at least one double bond. The urethane-urea-acrylic cast sheet materials exhibit excellent impact properties and desirable hardness while also maintaining optical properties such as low haze that can be comparable to that of conventional cast acrylic sheet.
