A process for providing a binder for mineral fibers, comprising the steps of:
- mixing together under reactive conditions an amine and an anhydride whereby water is added thereto, once substantially all the anhydride is dissolved in and/or reacted with the amine.
A binder comprising the reaction product of an amine, a first anhydride, a second anhydride and water and the polymeric part of the binder having a molecular weight of a maximum of about 2000.
A method of reducing emissions and improving the average molecular weight of a binder for mineral fibers, comprising an amine, a first aliphatic anhydride and a second aromatic anhydride, comprising adding water to the reaction mixture once the first anhydride is dissolved in the amine.
