| 摘要 |
<p>The invention relates to a composition consisting of a melamine solid suspended or dispersed in a resole resin. The method of the invention favors the intermolecular condensation polymerization reaction between phenol and melamine, rather than homopolymerization between phenol molecules or between melamine molecules. This invention reduces formaldehyde emissions by favoring a reaction whose by-product is water rather than formaldehyde. The compositions are useful for bonding glass fiber mats used for thermal and acoustical insulation.</p> |
