Abstract
A comparison between the molecular structure of conventional and low m olecular weight hydroxyl terminated polybutadienes (HTPBs) is presente d. The conventional HTPB samples were R45M, R45HT (Atochem), Liquiflex P and H (Petroflex, Brazil), and the low molecular weight ones were R 20LM (Atochem) and two laboratory synthesized materials. The structura l differences found were attributed to dissimilarities in fabrication processes for each type of HTPB. Some mechanistic pathways for the pol ymerization are suggested.
