VBC Product Properties

VBC is a dual functional monomer that can polymerize before or after functional reactions with the benzylic groups. VBC consists of a polymerizable double bond and a benzylic chloride group. By starting with VBC, you eliminate many of the challenges and costs of chloromethylating styrene at your facility.
