METSS proposes to design a novel polymer system based on polypropylene with covalently attached antioxidants

to mitigate issues with chemical permeation and water quality with current waterpipe materials. Polypropylene

was selected as it has inherently good physical properties and low permeability that will limit chemical migration

from the outside, addressing one critical factor impacting water quality. Covalently bonding the antioxidant to

the polymer backbone will address the other issue with water quality, which is migration of the conventional

antioxidant out of the plastic and into the water. The proposed solution has broad applicability to food contact

applications that use polypropylene. The Phase I program will address the production and characterization of the

antioxidant-modified polypropylene material. Development of a practical solution to improve water pipes

constructed of polypropylene will result in significant commercial benefits, including better water quality, cold

and hot water operational capability, and recyclability. Real-world applications include plastic tubes and pipes,

food packaging, and water and beverage bottles/containers.
