Process to Produce Polycarbamate, Polycarbamate Produced Thereby and a Coating Composition Comprising the Polycarbamate |
| 摘要 |
A process to prepare polycarbamate comprising adding urea to a polyol in the presence of at least one catalyst selected from the group consisting of compounds having the following formula MmZn; wherein M is a tetravalent metal, and Z is an anionic functionality or a functionality capable of forming a covalent bond with M and wherein n times a valence number of Z equals X and m times four equals Y wherein the absolute value of X equals the absolute value of Y is provided. Also provided are a polycarbamate produced according to the process and a coating composition comprising the polycarbamate. |
