The addition of IAD pendant groups to PB molecules results in a larger effective chain crosssectional area with consequent decrease in chain entanglements. This causes the rubber to be more complaint at low strains and strain rates. Simultaneously, the IAD structures give rise to polar and H‐bond interactions which cause the material to exhibit strong adhesion and to possess high green strength. As a result, the IAD‐PB is a relatively rare example of a synthetic polymer with good autoadhesive properties.
