<p>Method and the product thereof, whereby a thermoset or thermoplastic composition is produced by steps of mixing and reacting a partially or fully formylated polydiene with a formyl reactant selected from the group consisting of melamine, phenol, urea, and mixtures thereof. The present invention significantly reduces the formaldehyde offgassing problem of formaldehyde type resins by coupling the formaldehyde group to a polymer such as a polydiene and then crosslinking the resultant polymers through the formaldehyde group. Formaldehyde groups can be linked to polymers such as polydienes through an oxo or hydroformylation reaction.</p> |
