Notes:
The transition temperatures (TG) of unfractionated vinyl acetate polymers increase from 17° to 26° as the molecular weight increases from 14,000 to 104,000 and from 26° to 28° as the molecular weight increases from 104,000 to 1,120,000. The minimum molecular weight above which increase in molecular weight does not appreciably change TG is about 100,000. TG increases linearly with the reciprocal of the square root of the molecular weight.
