简介：

Poly(urethane-methacrylate)(PUA)plasticsheetswerepreparedfromisophoronediisocyanate(IPDI),differentkindsofpolyols,andβ-hydroxyethylmethacrylate(HEMA)inthepresenceofdibutytindilaurate(DBTL)ascatalystand2,2-azo-bis-iso-butyro-nitrile(AIBN)asinitiator.Thepropertiesofthematerialweremeasuredbydynamicmechanicalanalysis(DMA),wateruptakeandopticalpropertiestesting,andmechanicalperformancemeasurements.Theeffectofkindsofpolyolsonthefinalpropertieswasevaluated.Theresultsshowthatthetensilestrengthandglasstransitiontemperature(Tg)ofPUAdecreasewithincreasingthemolecularweightofpolyols.However,thelongerpolyolchaininthePUAsleadstothehigherimpactstrength.TheobtainedPUAspresentthegoodthermalandmechanicalproperties,lowwateruptake(below2.5%)andhightransparence(above90%).ThediversityofpropertiessuggeststhatthesePUAscanbeusedinawiderangeofexcellentopticalpolymerapplications.
