Abstract
A family of novel diazirine-based molecules is disclosed, as well as methods of manufacture and uses thereof. These compounds allow non-functionalized polymers, such as polyolefins, to crosslink via C—H insertion. Such a C—H insertion process is useful, for example, for forming protective topical coatings on low surface energy films, for the covalent adhesive bonding of such films, or for creating rigid 3-dimensional polymeric structures by in-situ doping and activation of the crosslinker. The disclosed crosslinkers can be activated thermally, by UV radiation or by an electric potential.
Claims14
A compound of Formula I:
- wherein:
- R, in each instance, is independently selected from the group consisting of alkyl and cycloalkyl;
- Ar is selected from the group consisting of null and aryl;
- L is a linker moiety selected from the group consisting of null, alkylene, and cycloalkylene;
- A is a cargo moiety, which may be absent;
- m is an integer from 1 to 4;
- and
- n is an integer from 1 to 4;
- with the provisos that Ar and L cannot both be null, m and n cannot both be 1 and that the compound is not 1,3-bis(3-(trifluoromethyl)-3H-diazirin-3-yl)benzene.
A method of crosslinking a polymer using a compound of Formula II:
- wherein:
- R, in each instance, is independently selected from the group consisting of alkyl and cycloalkyl;
- Ar is selected from the group consisting of null and aryl;
- L is a linker moiety selected from the group consisting of null, alkylene, cycloalkylene, ether, ketone, amide, ester and aryl;
- A is a cargo moiety, which may be absent;
- m is an integer from 1 to 4;
- and
- n is an integer from 1 to 4;
- with the provisos that Ar and L cannot both be null, m and n cannot both be 1.
