Claim 6:
7. The method of claim 1, wherein the monomeric mixture comprises:
(i) about 42 wt. % to about 55 wt. %, based on the total weight of the monomeric mixture, of the one or more cyclic lactams;
(ii) about 5 to about 25 wt. %, based on the total weight of the monomeric mixture, of the one or more non-bulky organosilicon-containing monomers;
(iii) about 10 to about 45 wt. %, based on the total weight of the monomeric mixture, of the one or more bulky siloxane monomers; and
(iv) a crosslinking agent mixture comprising (i) about 0.05 to about 2 wt. %, based on the total weight of the monomeric mixture, of the one or more first crosslinking agents and (ii) about 0.05 to about 3 wt. %, based on the total weight of the monomeric mixture, of the one or more second crosslinking agents.
