• recurring unit II is:
• recurring unit III is:
• wherein is Ar1 is selected from the group consisting of:
• and mixtures thereof;
• recurring unit IV is:
• —O—Ar2—X— IV
• wherein Ar2 is selected from the group consisting of:

• and wherein recurring unit I is present in an amount of from about 15 to about 60 mole percent, recurring unit II is present in an amount of from about 15 to about 60 mole percent, recurring unit III is present in an amount of from about 5 to about 20 mole percent, recurring unit IV is present in an amount of from about 5 to about 30 mole percent, and recurring unit V is selected from the group consisting of V(a), V(b), V(c) and (Vd) and is present in an amount of from about 7 to about 15 mole percent and wherein:
• (a) recurring units I and II combined are present in an amount of from about 50 to about 75 mole percent and
• (b) the polymer contains at least about 5 mole percent of recurring units of the formula:
• with the proviso that recurring unit II is present in an amount of at least about 30 mole percent, if and when the polymer also contains:
• in combination with a total from 0 to about 5 mole percent of units selected from the group consisting of units (Va), (Vb) and (Vd) and mixtures thereof.
