Polybutylene is composed of linear chains having an isotactic arrangement of ethyl side groups along the chain backbone. info@ncbi.nlm.nih.gov. Although polybutene formulations may vary in the molecular weight of the polymers, polybutene refers to the relatively low molecular weight polymers that are liquids at room temperature and pressure. To clarify the distinction, polybutene products may have average molecular weights from the hundreds to thousands of grams per mol, but polybutylene type formulations may have average molecular weights in the hundred of thousands to even millions of grams per mol. Butanediamide, N,N-bis3-(9Z)-9-octadecenylaminopropyl-, polybutenyl derivs. Once cooled, it turns into a soft, elastic material due to its partially tetragonal crystal structure.
