Abstract

The present application relates to a polymer composition comprising from 20 wt % to 30 wt % of a polycarbonate; from 40 wt % to 60 wt % of a polybutylene terephthalate; from 5 wt % to 30 wt % of a reinforcement fiber; from 1 wt % to 10 wt % of glass bubbles, and from 0.3 wt % to 2 wt % of transesterification inhibitor, all contents are based on the total weight of the composition. The polymer composition according to the present invention has improved adhesion to the metal (especially aluminum), even after annealing and anodizing processes are applied.
