Abstract:
1. A method of preparing periodic, semi-periodic, or semi-random polyethylene-co-acrylic acid or polyethylene-co-methacrylic acid comprising the steps of: providing a mixture comprising at least one 1-alkoxyalkyl ester substituted α,Ω-diene monomer of formula (1), at least one 1-alkoxyalkyl ester substituted cycloalkene monomer of formula (2), or a mixture thereof and a metathesis catalyst, polymerizing the monomers of said mixture to give a polymer of formula (3), and hydrogenating by introducing a hydrogenation catalyst and hydrogen to the polymer of formula (3) to yield periodic, semi-periodic, or semi-random polyethylene-co-acrylic acid or polyethylene-co-methacrylic acid of formula (4), wherein in formulas (1), (2), (3), and (4): x and y are independently 1 to 20; w and z are independently 1 to 5, where w+z is 2 to 6, m and n are independently 0 to 10,000 where n+m is 50 to 10,000; R and R′ are independently an alkyl group of 1 to 6 carbons; and R″ is II or an alkyl group of 1 to 6 carbons.
