Abstract
The invention relates to polymer compositions comprising PCT (poly((cyclohexylene-dimethylene)terephthalate)) polymer and a fibrous glass filler having a non-circular cross-sectional aspect ratio of greater than at or about 4.
Claims21
A polymer composition consisting of:
- a) a PCT (poly(cyclohexylene-dimethylene)terephthalate) polymer in an amount from about 30 to about 95 wt % of the polymer composition,
- b) a fibrous glass filler having a non-circular cross-sectional aspect ratio of greater than at or about 4 in an amount from about 5 to about 70 wt % of the polymer composition,
- c) up to about 40 wt % of other thermoplastic polymers selected from the group consisting of poly(ethylene terephthalate), poly(propylene terephthalate), poly(butylene terephthalate), and poly(naphthalene terephthalate), and
- d) optionally, one or more additives selected from the group consisting of a polymeric toughener, one or more oxidative stabilizers, a lubricant, a UV light stabilizer, an antistatic agent, a coloring agent, a nucleating agent, and one or more reinforcing agents.
