Abstract:
Compositions of matter including articles derived from (a) from 5 to 99.99 wt % of a modified polybutylene terephthalate random copolymer that (1) is derived from polyethylene terephthalate and (2) contains a at least one residue derived from polyethylene terephthalate selected from the group consisting of antimony, germanium, diethylene glycol groups, isophthalic acid groups, cis isomer of cyclohexane dimethanol, trans isomer of cyclohexane dimethanol, sodium benzoate, alkali salts, napthalane dicarboxylic acids, 1,3-propane diols, cobalt, cobalt-containing compounds, and combinations thereof, and (b) from 0.01 to 95 wt. % of a member selected from the group consisting of (1) fillers, (2) a carboxy reactive component, (3) polyethyelene terephthalate, (4) a component including a polycarbonate and an impact modifier. The articles may be derived from various conversion processes, e.g., injection molding processes, extrusion processes, thermoforming processes, melt-blown process.
