Detailed introduction of "Polyisobutylene PB series imported high-quality adhesive raw materials from Daelim, South Korea"

Polyisobutylene PB series imported high-quality adhesive raw materials from Daelim, South KoreaBasic introduction Polyisobutylene (PIB) is a polymer obtained from isobutylene by positive ionization polymerization, and its molecular weight can range from hundreds to millions. It is a typical saturated linear polymer. The main body of the molecular chain does not contain double bonds, and there is no long branch. Its structural unit is -(CH2-C(CH3)2)-, which has no asymmetric carbon atoms, and the structural units are connected in a regular sequence from head to tail.
