Poly aryl ether ketone polymer blends

A filled polymer blend comprising a mixture of:

• from 2 to 99 wt. % of a resin blend comprising:
• a first resin component comprising one or more polyaryl ether ketones;
• and
• a second resin component comprising one or more polysulfone etherimides having greater than or equal to 50 mole % of the polymer linkages containing at least one aryl sulfone group and comprising the reaction product of a dianhydride monomer and a diamine monomer,
• wherein the ratio of the first component to the second component, in parts by weight is from 99:1 to 60:40;
• wherein:
• 1) the dianhydride monomer is selected from the group consisting of oxydiphthalic anhydrides, bisphenol A dianhydride (BPADA), disulfone dianhydride, bis(carbophenoxy phenyl)hexafluoro propane dianhydride, pyromellitic dianhydride (PMDA), biphenyl dianhydride, and mixtures thereof;
• and,
• 2) the diamine monomer is selected from the group consisting of diamino diphenyl sulfone (DDS), m-phenylene diamine (mPD), p-phenylene diamine (pPD), 4,4′-oxydianiline (ODA), 1,3-bis(4-aminophenoxy benzene) and bis(aminophenoxy phenyl)sulfones (BAPS);
• and
• from 1 to 98 wt. % of at least one filler;
• wherein the at least one filler has a weight loss (under nitrogen) of 10% or less at 300° C., as determined by thermal gravimetric analyses ASTM method E1868,
• wherein the polymer blend has a melt viscosity of 200 to 1000 Pa-s at 380° C., and less than a 50% change in initial melt viscosity after 10 minutes at 380° C., and
• wherein the wt. % of resin blend and filler are based upon the combined weight of resin blend and filler.
