Abstract

An epoxy terminated polyester having the structure

wherein R 1 — is

G— is

j is 0 to 5, —R 2 — is a divalent organic group, —R 22 — is a divalent alkyl group, and —R 22 — is a divalent alkyl group.

First claim

The invention claimed is:

1. An epoxy terminated polyester having the structure

wherein R 1 — is

G— is

j is 0 to 5, —R 2 — is a divalent organic group having the structure

wherein —R 4 — and —R 5 — is each independently a divalent organic group, and wherein said p is 0 to 20; wherein —R 3 — is either —(CH2) q — or

wherein q is 1 to 8;
and wherein —R 21 — is a divalent alkyl group, and every —R 22 — is a divalent alkyl group.

2. The polyester of claim 1 , wherein said —R 21 — has 3 carbon atoms and every —R 22 — has 3 carbon atoms.

3. The polyester of claim 2 , wherein at least one —R 22 — has the structure selected from

4. The polyester of claim 1 , wherein said —R 4 — is either —CH 2 —CH 2 — or —CH 2 —CH 2 —O—CH 2 —CH 2 —.

5. The polyester of claim 1 , wherein said —R 21 — has 5 or fewer carbon atoms, and every said —R 22 — has 5 or fewer carbon atoms.
