Plastics & Polymers Enhancing Polymer Performance

DMAP

DMAP is a superacylation catalyst that is effective for even the most difficult transformations. It has been used in agricultural, pharmaceutical, polymer and chemical process industries. It is a consistent, predictable basic nucleophilic catalyst for epoxy, urethane and hybrid polymer systems.

Polyurethanes

DMAP catalyses the reaction of isocyanates with either alcohols or phenols to afford the polyurethanes. The mechanism of this reaction is thought to be one of base catalysis, rather than the more usual mode of action, nucleophilic catalysis. Often reactions occur faster and at lower temperatures which affords less degradation impacting, which may impact product color.

Polyamides

There are numerous examples of DMAP being used in the manufacture of polyamides, improving rate of reaction and selectivity, often with beneficial improvements in properties due to fewer by-products

Polyesters

DMAP catalyses the reaction of lactides, esters and the like. Reactions occur faster and at lower temperatures which affords less degradation.

Polycarbonates

DMAP catalyses the reaction of cyclic carbonates by ring opening in the presence of alcohols to afford polycarbonates

Vertellus offers two grades of N,N-Dimethyl-4-aminopyridine, the standard flaked DMAP and the Easy-Flo® DMAP grade. Easy-Flo® DMAP grade is a pelletized product that improves product handling by improving flowability, reducing dust and helping prevent product compaction.
