Improved process for the preparation of advanced resins. |
摘要 |
The invention provides for a process for the preparation of an advanced epoxy resin by reaction of a compound having on average more than one epoxy group per molecule and a compound having on average one or more hydroxyl group or carboxyl group per molecule in the presence of a catalyst at elevated temperature, the process comprising (1) mixing the epoxy compound, the hydroxyl compound or the carboxyl compound and the catalyst, and (2) transferring the mixture as a feedstream to a surface exposed to an elevated temperature sufficient to produce an advanced epoxy resin which is at least intermittently moving with respect to the feedstream. In a preferred embodiment an endless conveyer belt with additional heating means and optional cooling means are used. |
