A new class of amines is incorporated into phtopolymerizable systems employing type I or type II photoinitiators. These amines are trialkylamines having a total of 10 to about 36 carbon atoms in the molecule and wherein at least one alkyl group has a chain length of at least 8 carbon atoms. Preferably, one or two of the alkyl groups are methyl or ethyl or one of each. Short chain amines as defined herein provide synergistic results when used with such trialkylamines.

Class of amine coinitiators in photoinitiated polymerizations

Novel benzophenone derivatives and methods of making and using the same are disclosed. The novel compounds can display highly active photoinitiation and photopolymerization properties.

Aminobenzophenones and photopolymerizable compositions including the same

Stabilized pre-promoted unsaturated polymer resin systems that include a tertiary aromatic amine cure promoter. The stabilized curable resins systems can include a vinyl ester resin.

Stabilized unsaturated polymer resin compositions and methods of using the same

Methods of promoting the cure of unsaturated polymer resins with a peroxide initiator by including as a promotor N-alkyl-N-(2-hydroxyalkyl)-p-toluidines. The use of the tertiary aromatic amines as a promotor provides a fast cure at a wide range of temperatures. Polymerizable compositions and methods of applying the same to a surface are also described.

Methods of curing unsaturated polymers using tertiary aromatic amine cure promoters

Methods of curing unsaturated polymers using tertiary aromatic amine

Processes for preparing aromatic carboxylic acids. Cinnamaldehyde is hydrogenated to produce a mixture of hydrogenation products, namely, hydrocinnamaldehyde and hydrocinnamic alcohol. The mixture is then oxidized using a suitable oxidizing agent to substantially completely convert both hydrocinnamaldehyde and hydrocinnamic alcohol to hydrocinnamic acid.
