POLYETHYLENE TEREPHTHALATE COMPOSITIONS

摘要

Articles having improved low temperature impact strength are formed from thermoplastic resin compositions comprised of (a) from about 92 to about 99 weight percent polyethylene terephthalate having an intrinsic viscosity of from at least about 0.7 dl/g; (b) from about 1 to about 8 weight percent of a polyethylene ionomer; and (c) optionally an effective amount of heat stabilizer. Such thermoplastic resin compositions are thermoformed into thin walled articles such as dual-ovenable trays, the resins having a crystallinity within the range of about 10% to about 40%.
