Claims
- 1. A method for making an oligomer of the general formula: ##STR23## wherein Ar=an aromatic moiety selected from the group consisting of phenyl, biphenyl, naphthyl, and azalinyl;
- w=3 or 4;
- Y= ##STR24## n=1 or 2; ##STR25## R.sub.1 =any of lower alkyl, lower alkoxy, or aryl; j=0, 1, or 2;
- G=--CH.sub.2 --, --S--, --O--, or --SO.sub.2 --,
- Me=methyl; and
- E=allyl or methallyl,
- comprising the steps of:
- (a) reacting Ar--X).sub.w with at least w moles of phenol in an Ullmann ether synthesis in DMAC and a base in the presence of an Ullmann copper catalyst to form an Ar-- ether intermediate; and (b) reacting the Ar-- ether intermediate with at least w moles of Y--COX under Friedel-Crafts conditions in a suitable solvent to produce the oligomer, wherein X=halogen.
- 2. A method for making an oligomer of the general formula: ##STR26## wherein Ar=an aromatic moiety selected from the group consisting of phenyl, biphenyl, naphthyl, and azalinyl;
- w=3 or 4;
- Y= ##STR27## n=1 or 2; Z= ##STR28## Me=methyl; E=allyl or methallyl;
- Q=an organic, divalent radical selected from the group consisting of: ##STR29## q=--SO.sub.2 --, --CO--, --S--, or --(CF.sub.3).sub.2 C--; R.sub.1 =any of lower alkyl, lower alkoxy, or aryl;
- X=halogen;
- j=0, 1, or 2; and
- G=--CH.sub.2 --, --S--, --O--, or --SO.sub.2 --,
- comprising the steps:
- (a) reacting Ar--(X).sub.w with at least w moles of phenol in an Ullmann ether synthesis in DMAC and a base and in the presence of an Ullmann copper catalyst to form an Ar-- ether intermediate; and
- (b) reacting the Ar-- ether intermediate with at least w moles of a diacid halide of the general formula XOC--Q--COX and with at least w moles of ##STR30## under Friedel-Crafts conditions in a suitable solvent to produce the oligomer.
