摘要 |
The invention relates to a process for the preparation of an advanced 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 than one nucleophile bearing active hydrogen such as aromatic hydroxyl group, carboxyl group or amino group, per molecule, in the presence of a catalyst at elevated temperature, the process comprising (1) mixing the epoxy compound, the aromatic hydroxyl compound or the carboxyl compound and the catalyst, and (2) transferring the mixture, as a feedstream to a surface 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.
