## Abstract

An epoxy terminated polyester having the structure wherein R1— is G— is j is 0 to 5, —R2— is a divalent organic group, —R22— is a divalent alkyl group, and —R22— is a divalent alkyl group.

## Claims

### Claim 1

An epoxy terminated polyester having the structure
wherein R1— is
G— is
j is 0 to 5, —R2— is a divalent organic group having the structure
wherein —R4— and —R5— is each independently a divalent organic group, and wherein said p is 0 to 20; wherein —R3— is either —(CH2)q— or
wherein q is 1 to 8;
and wherein —R21— is a divalent alkyl group, and every —R22— is a divalent alkyl group.

### Claim 2 (depends on 1)

The polyester of claim 1, wherein said —R21— has 3 carbon atoms and every —R22— has 3 carbon atoms.

### Claim 3 (depends on 2)

The polyester of claim 2, wherein at least one —R22— has the structure selected from

### Claim 4 (depends on 1)

The polyester of claim 1, wherein said —R4— is either —CH2—CH2— or —CH2—CH2—O—CH2—CH2—.

### Claim 5 (depends on 1)

The polyester of claim 1, wherein said —R21— has 5 or fewer carbon atoms, and every said —R22— has 5 or fewer carbon atoms.
