Abstract
Provided are sulfone-containing polyarylene polymers. Also provided are monomers and processes for preparing the polymers. The polyarylene polymers are suitable for use as engineering polymers.
Claims
exact text as granted — not AI-modified1 . A polymer comprising repeating units of Formula (I):
where T is a bulky aromatic group.
2 . The polymer of claim 1 that has a number average molecular weight of at least about 5,000.
3 . The polymer of claim 1 wherein T is phenyl.
4 . The polymer of claim 1 further comprising repeating units of Formula (II):
where T′ is a bulky aromatic group.
5 . The polymer of claim 4 that has a number average molecular weight of at least about 5,000.
6 . The polymer of claim 4 wherein T′ is phenyl.
7 . A compound of Formula (IA):
where T is a bulky aromatic group and X is Br or Cl.
8 . The compound of claim 7 where T is phenyl
9 . The compound of claim 7 where is Cl.
10 . A process for preparing a polymer comprising polymerizing a monomer of Formula (IA)
wherein T is a bulky aromatic group and X is independently Br or Cl.
11 . The process of claim 10 where T is phenyl
12 . The process of claim 10 where X is Cl.
13 . The process of claim 10 wherein the polymer has a number average molecular weight of at least about 5,000.
14 . The process of claim 10 wherein the process comprises polymerizing a monomer of Formula (IA) and a monomer of Formula (IIA)
wherein T′ is a bulky aromatic group and X′ is independently Br or Cl.
15 . The process of claim 10 where T and T′ are phenyl
16 . The process of claim 10 where X and X′ are Cl.
17 . The process of claim 14 wherein the polymer has a number average molecular weight of at least about 5,000.
18 . The process of claim 10 wherein the polymerization is done in the presence of a zerovalent transition metal and a neutral ligand in the form of a complex.
19 . The process of claim 18 wherein the zerovalent transition metal is palladium or nickel.
20 . The process of claim 18 wherein the zerovalent transition metal is bis(1,5-cyclooctadiene)nickel(0) and the neutral ligand is 2,2′-bipyridine.Cited by (0)
