Method of forming a polyurethane material with a metallized polyhedral oligomeric silsesquioxane compound

摘要

A method to form a urethane material, the method comprises blending and reacting at least one isocyanate, at least one isocyanate reactive compound and a metallized polyhedral oligomeric silsesquioxane to provide said urethane material, the metallized polyhedral oligomeric silsesquioxane is a dimeric structure with general formula;wherein

M represents a metal providing a 6-coordinated metal center, x and y being 1, R1O and R2O represent an alkoxide bridging the 6-coordinated metal centers, R3OH and R4OH represent an alcohol ligand and each of R5, to R18 is selected from the group consisting of alkyl-, polyether- and polyester ligands.

1. A method to form a urethane material, the method comprises the steps of:
providing at least one isocyanate; providing at least one isocyanate reactive compound; providing a metallized polyhedral oligomeric silsesquioxane wherein the metallized polyhedral oligomeric silsesquioxane is different from the at least one isocyanate reactive compound; blending and reacting said at least one isocyanate, at least one isocyanate reactive compound and said metallized polyhedral oligomeric silsesquioxane to provide said urethane material, wherein said metallized polyhedral oligomeric silsesquioxane is a dimeric structure with general formula whereinM1 and M2 represent a metal providing a 6-coordinated metal center;x=1;y=1;R1O and R2O each independently represent an alkoxide bridging said 6-coordinated metal centers;R3OH and R4OH each independently represent an alcohol ligandEach of R5, R6, R7, R8, R9, R10, R11, R12, R13, R14, R15, R16, R17, R18 is selected from the group consisting of alkyl ligands.
