ABSTRACT:
This invention relates to polymeric thermoplastic moldable compositions comprising poly(alkylene carbonates), which are useful in manufacturing of articles which may be manipulated and shaped by their user, but regain their shape after distortion. These compositions are free from toxic compounds and have a glass transition temperature from about 15° C. to about 132° C. These compositions are useful in manufacturing of articles such as toys, utensils to convey solids or liquids to the mouth, soothing articles (i.e., teething rings and pacifiers) and articles which support food (i.e., candy/confection sticks or holders.) They are most useful in manufacturing of children's toys and products.
