Abstract
The metal-containing compounds which have amine substituents at each ends of the molecular chain were prepared and were then added in the process of one shot mixing method of polyurethane formation. And then, the mechanical and thermal properties of the product were examined.
Amine compounds prepared are bis (4-amino phenoxy) dimethyl silane, 1, 4-bis (4-amino phenoxy dimethyl siloxy) benzene and di-butyltin bis (4-amino benzoate).
As the results, both the tensile strength and elongation at break of polyurethane increased with increasing the amount of these compounds, and stress relaxation time was found to be longer than that of the conrol sample.
