ABSTRACT:
The labor costs associated with manufacturing wooden articles often represent a substantial portion of the total cost of producing the wooden article. This invention discloses a polymeric composition which can be easily molded into articles which have physical properties which are very similar to those of wood. By utilizing the polymeric composition and techniques of this invention, it is possible to manufacture a wide variety of wood-like articles by molding at reduced costs. This invention specifically reveals a polymeric composition which can be molded into articles having wood-like physical properties which is comprised of (1) from about 80 to about 99 weight percent polyethylene terephthalate, (2) from about 1 to about 20 weight percent of a polycarbonate, and (3) from about 0.3 to about 2 weight percent of 5-phenyltetrazole. These polymeric compositions can be prepared utilizing scrap polyethylene terephthalate, such as recycled polyethylene terephthalate beverage bottles.
