1. A process comprising the steps of:
- i) mixing at least one monomer with a solvent;
ii) adding an initiator to the solvent or the mixture of the solvent and the at least one monomer, wherein the molar ratio of the one or more monomers to the initiator is about 50;
1 or more;
iii) anionically polymerizing the at least one monomer to form a polymer having a weight average molecular weight of about 3000 daltons or more, wherein the at least one monomer includes including a 1,1-disubstituted alkene compound in solution.

Abstract
The present teachings show that it is possible to polymerize 1,1-disubstituted alkene compounds in a solution (for example using one or more solvents). Polymerization of 1,1-disubstituted alkene compounds in a solution provides opportunities to better control the polymerization compared with bulk polymerization. The solution polymerization techniques can be employed for preparing homopolymers, copolymers (e.g., random copolymers), and block copolymers.
