Abstract: This disclosure provides polymeric materials comprising polymer crystals, methods and resins for making the same, and objects and appliances made from said polymeric materials. Polymeric materials having polymer crystals provide favorable properties, such as enhanced durability and rigidity. This disclosure also provides polymeric materials comprising a crystalline phase comprising at least one polymer crystal, as well as an amorphous phase comprising at least one amorphous polymer. The crystalline phase can confer rigidity to the polymeric material, while the amorphous phase can confer elasticity and flexibility.
