In chemically activated cements, the initiators are tertiary amines
that are activated by benzoyl peroxide, and the polymerization reaction occurs even in regions where the light from a light curing unit cannot reach the resin cement layer.
Camphorquinone is an example of a photoinitiator that requires a co-initiator such as a tertiary amine
for an efficient polymerization process to occur.
DMDEE high-boiling tertiary amine
with a balanced reactivity to blowing and gelation reactions.
Strong Lewis bases as tertiary amines
catalyze the curing (Hagnauer and Pearce, 1992; Barton, 1986; Morgan, 1985; Steinmann, 1989).
Immobilization of Aromatic Tertiary Amine
Groups Onto Attapulgite
4 kJ/mol while 4,4'-DDS decreases cohesive energy by about 27 kJ/mol when forming tertiary amine
moieties during cure .
The acquisition enhances Pilot Chemical's household, industrial and institutional, personal care and oil and gas product portfolios, strengthening its offering by adding registered and nonregistered biocidal quats and tertiary amine
derivatives, according to the company.
In addition, they have developed tertiary amine
catalyzed ring-opening reactions of aziridines with various nucleophiles, such as amines and thiols .
The latter can be worked around by using corrosion resistant tanks, pipes, and fittings, but epoxide resins reacted with tertiary amine
salts or amines to form quaternary ammonium salts or amine salts provide higher bath pH and lower corrosivity.
The resulting 2[degrees] amine reacts with a second-activated epoxide to yield a tertiary amine
4] alkoxy group and at least one primary, secondary or tertiary amine
group, the particulate filler material present in the composition at a level of from 0.
The copolymers are constructed from tertiary amine
methacrylates and poly(ethylene glycol) methacrylates.
