| 20080249203 | Class of Amine Coinitiators in Photoinitiated Polymerizations - A new class of amines is incorporated into photopolymerizable 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. | 10-09-2008 |
| 20080262187 | Blends of Diamines Having Reduced Color - This invention provides a blend which comprises (i) at least one aromatic primary diamine, with which has been blended a color-minimizing amount of at least one N,N-dmydrocarbylhydroxylamine, wherein the aromatic primary diamine is in the form of one benzene ring having two primary amino groups on the ling, which amino groups are meta or para relative to each other, and in which each position ortho to a primary amino group bears an alkyl group, and (ii) at least one aromatic secondary diamine having a Gardner color number no more than about 7, wherein said aromatic secondary diamine either is in the form of one benzene ring having two secondary amino groups on the ring, or is in the form of two benzene rings connected by an alkylene bridge and having one secondary amino group on each ring. Optionally, at least one N,N-dihydrocarbylhydroxylamine has been blended with the aromatic secondary diamine. | 10-23-2008 |
| 20080315155 | Diamines Having Reduced Color - This invention provides compositions which comprise at least one aromatic secondary diamine having a Gardner color number no more than about 6. The aromatic secondary diamine either is in the form of one benzene ring having two secondary amino groups on the ring, or is in the form of two benzene rings connected by an alkylene bridge and having one secondary amino group on each ring. At least one N,N′-dihydrocarbylhydroxylamine is optionally present in the composition. Processes for producing such compositions are also provided. | 12-25-2008 |
| 20100160592 | Formulations For Reaction Injection Molding And For Spray Systems - This invention provides articles made by reaction injection molding and spray coatings, and processes for forming such articles and coatings. The coatings and articles are polyureas or polyurea-urethanes. The ingredients used to form the coatings and articles comprise at least (A) an aromatic polyisocyanate and (B) a mixture formed from components comprised of (i) at least one polyol and/or at least one polyetheramine, (ii) an aromatic primary diamine, and (iii) an aliphatic secondary diamine which has about twelve to about forty carbon atoms and in which the having amino hydrocarbyl groups are secondary or tertiary hydrocarbyl groups. | 06-24-2010 |
| 20110137005 | Chain Extenders - This invention provides chain extender compositions. These compositions comprise | 06-09-2011 |
