Abstract
This invention relates to a process for producing a moisture curable silyl-terminated polymer which comprises the steps of: (a) reacting a terminally-unsaturated monol (preferably a polyether or polyester monol) with a polyfunctional hydroxyl-reactive compound selected from the group consisting of polyisocyanates and organic polacyl compounds in a molar ratio of one mole of monol for each equivalent of functionality on said polyfunctional hydroxyl-reactive moiety, to provide a terminally-unsaturated polymer having terminal unsaturation at each end thereof; and (b) reacting said terminally-unsaturated polymer with a dialkoxyalkylsilane to form a dialkoxyalkylsilyl-terminated polymer capable of curing upon contact with moisture.
Claims24
A process for producing a moisture curable silyl-terminated polymer which comprises the steps of:
- (a) reacting a terminally-unsaturated polyester monol with a polyfunctional hydroxyl-reactive compound selected from the group consisting of polyisocyanates and organic polyacyl compounds, in a molar ratio of about one mole of monol for each equivalent of functionality on said polyfunctional hydroxyl-reactive compound, to provide a terminally-unsaturated polymer having terminal unsaturation at each end thereof;
- and
- (b) reacting said terminally-unsaturated polymer with a dialkoxyalkylsilane to form a dialkoxyalkylsilyl-terminated polymer capable of curing upon contact with moisture.
A silyl-terminated polymer selected from the group consisting of polyesters and combinations thereof, bound together by a polyfunctional hydroxyl-reactive compound selected from the group consisting of polyisocyanates and organic polyacyl compounds, said polymer being made by reacting a polyester monol with said polyfunctional hydroxyl-reactive compound in a molar ratio of about one mole of monol for each equivalent of functionality on said polyfunctional hydroxyl-reactive compound.
A filled polymer comprising a filler and a silyl-terminated polymer selected from the group consisting of polyesters and combinations thereof, bound together by a polyfunctional hydroxyl-reactive compound selected from the group consisting of polyisocyanates and organic polyacyl compounds, said polymer being made by reacting a polyester monol with said polyfunctional hydroxyl-reactive compound in a molar ratio of about one mole of monol for each equivalent of functionality on said polyfunctional hydroxyl-reactive compound.
A cured rubbery polymer product made by a process comprising contacting moisture with a silyl-terminated polymer selected from the group consisting of polyesters and combinations thereof, bound together by a polyfunctional hydroxyl-reactive compound selected from the group consisting of polyisocyanates and organic polyacyl compounds, said polymer being made by reacting a polyester monol with said polyfunctional hydroxyl-reactive compound in a molar ratio of about one mole of monol for each equivalent of functionality on said polyfunctional hydroxyl-reactive compound.
A terminally-unsaturated polymer having terminal unsaturation at each end thereof wherein said polymer is produced by a process of reacting a terminally-unsaturated polyester monol with a polyfunctional hydroxyl-reactive compound selected from the group consisting of polyisocyanates and organic polyacyl compounds in a molar ratio of about one mole of monol for each equivalent of functionality on said polyfunctional hydroxyl-reactive moiety.
A cured rubbery polymer product made by a process comprising contacting a polyamine or polyalcohol, or combination thereof, with a silyl-terminated polymer selected from the group consisting of polyesters and combinations thereof, bound together by a polyfunctional hydroxyl-reactive compound selected from the group consisting of polyisocyanates and organic polyacyl compounds, said polymer being made by reacting a monol with said polyfunctional hydroxyl-reactive compound in a molar ratio of about one mole of monol for each equivalent of functionality on said polyfunctional hydroxyl-reactive compound.
