Polyvinylpyrrolidone (PVP)
In the Pharmaceutical Industry:
the resulting product is the corresponding poly(isobutylene)-b-poly(ethylene oxide) diblock copolymer
PVP is used to slow down spermatozoa in order to capture them for procedures like intracytoplasmic sperm injection (ICSI)
PIB-phenol Masse:1 g Polyvinylpyrrolidone (PVP)Polyisobutene phenol, polyisobutylene phenol, PIB phenol, or polyisobutenyl phenol, hydroxyl terminated. Used as an educt for further reactions to blockcopolymers or fuel additives. Polyisobutene phenols are obtained by alkylation of an aromatic hydroxy compound with essentially homopolymeric polyisobutenes in the presence of a Lewis acidic alkylation catalyst. Polyisobutene phenol is an important starting product for the production of fuel detergents
