Abstract
The invention is generally directed to sports bottles and other articles produced by blow molding from polymeric materials containing isosorbide having glass transition temperatures ranging from 90° C. to 130° C., as well as to processes for producing them. These articles can be exposed to water at high temperatures and can be produced by using a suitable combination of a stretch ratio of less than 3× and a preform temperature at least 20° C. greater than the glass transition temperature (Tg) of the polymeric material.
