Abstract

An epoxy terminated polyester having the structure

wherein R 1 — is

G- is

-A- is a divalent alkyl group, —CA- is a divalent cycloalkyl group, and —R 2 — is a divalent organic group.

First claim

The invention claimed is:

1. An epoxy terminated polyester having the structure

wherein R 1 — is

G- is

-A- is a divalent alkyl group, —CA- is a divalent cycloalkyl group, and —R 2 — is

wherein said —R 4 — is a divalent organic group, and wherein said p is 0 to 20, and wherein said —R 3 — and —R 5 — is each independently selected from the group consisting of aliphatic groups having 12 or fewer carbon atoms and aromatic groups.

2. The polyester of claim 1 , wherein said -A- is —(CH 2 ) n — wherein n is 1 to 6.

3. The polyester of claim 1 , wherein said —CA- is

4. The polyester of claim 1 , wherein said —R 3 — is either —(CH 2 ) q — or

wherein q is 1 to 8.

5. 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 —.
