Abstract
A method of initiating polymerization of a composition formed of a 1,1-disubstituted alkene compound includes contacting the composition with a substrate and passing an electrical charge through the composition. The composition can also be electrografted to the substrate or include conductive synergists.
Claims20
A method of initiating polymerization comprising:
- contacting a polymerizable composition with a substrate, the polymerizable composition comprising one or more 1,1-disubstituted alkene compounds;
- and
- passing an electrical charge through the polymerizable composition to initiate polymerization;
- and
- wherein the polymerizable composition undergoes living anionic polymerization after polymerization is initiated.
2 more elements
A method of initiating polymerization comprising:
- contacting a polymerizable composition with a substrate, the polymerizable composition comprising one or more 1,1-disubstituted alkene compounds and one or more conductive synergists selected from the group of non-nucleophilic conductive materials;
- and
- passing an electrical charge through the polymerizable composition to initiate polymerization;
- and
- wherein the one or more conductive synergists reduce the set time of the polymerizable composition to about 20 minutes or less once polymerization is initiated.
2 more elements
A method of initiating polymerization comprising:
- contacting a polymerizable composition with a substrate, the polymerizable composition comprising one or more 1,1-disubstituted alkene compounds and one or more acid stabilizers and one or more free radical stabilizers, and wherein the one or more acid stabilizers and the one or more free radical stabilizers are included in a ratio of about 10:100 to a ratio of 10:1,000 or more;
- and
- passing an electrical charge through the polymerizable composition to initiate polymerization.
