摘要:
A method for obtaining polyester resin products having a desired strength and a mixture used in a method for obtaining polyester resin products having a desired strength. In the method and mixture a carbodiimide compound is added to a polyester resin. According to the method and mixture, polyester resin pellets having a desired strength can be obtained by adding a carbodiimide compound to a recovered polyester resin such as a recovered PET resin. Strength of the polyester resin during processing of the polyester resin is maintained.
