View Patent ↗A process for preparing moisture curable compounds and moisture curable compositions prepared from the product of that process is provided.
1. A process for preparing aminoalkylalkoxysilane-functionalized hydrocarbon compounds, comprising:
Providing (a)
L is alkyl, poly(alkyl) or poly(acrylate), alkylene or poly(alkylene), alkenyl or poly(alkenyl), alkenylene or poly(alkenylene), aromatic or an aromatic ring system, X is a leaving group, R′ is alkyl, and n is 1-4, or
L is alkyl, poly(alkyl) or poly(acrylate), alkylene or poly(alkylene), alkenyl or poly(alkenyl), alkenylene or poly(alkenylene), aromatic or an aromatic ring system, X is a leaving group, R″ is alkyl, and n is 1-4, (b) an aminoalkylalkoxysilane, (c) base, and (d) organic solvent in a vessel and mixing (a)-(d) for a time sufficient to form an aminoalkylalkoxysilane-functionalized hydrocarbon compound.
2. The process of claim 1 , wherein X is a halogen, tosylate or mesylate.
3. The process of claim 1 , wherein X is a halogen selected from chlorine, bromine or iodine.
4. The process of claim 1 , the base is potassium carbonate or a trialkyl amine.
5. The process of claim 1 , wherein the organic solvent is acetonitrile.
6. The process of claim 1 , wherein mixing occurs at a temperature of reflux.
7. The process of claim 1 , wherein mixing at reflux occurs for a period of time of about 2 to about 24 hours.
8. The process of claim 1 , wherein mixing at reflux occurs for a period of time of about 2 to about 24 hours to achieve a yield of greater than about 90% of the aminoalkyl alkoxysilane-functionalized hydrocarbon compound.
9. The process of claim 1 , wherein the compound shown in structure I or II is made by a controlled radical polymerization technique.
10. An aminoalkyl alkoxysilane-functionalized hydrocarbon compound made in accordance with the process of claim 1 .
11. A moisture curable composition, comprising:
(a) an aminoalkyl alkoxysilane-functionalized hydrocarbon compound made in accordance with the process of claim 1 ; and
(b) a moisture cure calayst.
12. The composition of claim 11 , further comprising one or more of a filler component, a toughening component, a plasticizier component and a cross linker component.
