A polymer composition comprising a mixture of a) a first resin component comprising a polyaryl ether ketone, a polyaryl ketone, a polyether ketone, a polyether ether ketone, or a combination of two or more of the foregoing, and b) a second resin component comprising a specific type of copolycarbonate, wherein the mixture has at least two glass transition temperatures, as measured by ASTM method D5418, wherein the first glass transition temperature is from 120 to 160° C. and the second glass transition temperature is from 170 to 280° C. is disclosed. The compositions have improved properties such as improved load bearing capability at high temperature, better impact strength, and a high crystallization temperature. |
