Patent ID: 7122880

Claim:
A mixture of an at least one chemical reagent for producing a performance material having a dielectric constant of about 3.7 or less, the mixture comprising: an at least one silica source; an at least one porogen; a carboxylate selected from the group consisting of a carboxylic acid, a carboxylate anion, a carboxylic acid ester, or combinations thereof; a strong acid catalyst that has a pKa that is 2 or less and a strong base catalyst that has a pKa of its conjugate acid of greater than 12 in an amount sufficient to adjust a pAcid value of the mixture to a range of from 2.2 to 9; and an ionic additive, provided that if the at least one chemical reagent has a metal impurity level of 1 ppm or greater then the at least one chemical reagent is purified prior to adding to the mixture.
