Claims5
A method of making an oxidized polyethylene, comprising mixing a polyethylene, a metal catalyst, and an oxidizing agent;
- wherein:
- the oxidized polyethylene comprises a first oxidized subunit, a second oxidized subunit, and a non-oxidized subunit;
- the polyethylene comprises a non-oxidized subunit;
- the first oxidized subunit has the formula:
- the second oxidized subunit has the formula:
- the non-oxidized subunit has the formula:
- the ratio of the first and second oxidized subunits to the non-oxidized subunit in the oxidized polyethylene is from 1:10,000 to 1:5;
- the oxidized polyethylene has a number average molecular weight from 600 Da to 20,000,000 Da;
- wherein the metal catalyst is a ruthenium catalyst or an iron catalyst;
- and
- wherein a sum of a chloride subunit of formula
- and an ester subunit of formula
- of the oxidized polyethylene is less than 6% of a sum of the first oxidized subunit and the second oxidized subunit of the oxidized polyethylene.
