Abstract:

The hexachloroantimonate salt of the alpha, alpha, alpha, alpha- tetraphenyl-p-xylyl biscarbonium ion has been investigated as an initiator of cationic polymerization of vinyl compounds. This biscarbonium ion salt was found to be ineffective for initiating polymerization of vinyl aliphatic compounds, but effective for initiating polymerization of vinyl ethers. The mechanism of vinyl ether polymerization with this initiator was studied by end-capping reactions. The initiator was found to be incorporated into the polymer indicating an addition mechanism, but no evidence of end-capping groups was found, indicating the absence of living dicationic polymer chains.
