Abstract
Abstract A method is provided for electroinitiating cationic polymerization on the surface of a metal substrate or a metallized nonconducting substrate. The conducting substrate is used as the anode in an electrolyzed bath of a cationically polymerizable organic material, and an effective amount of an arylonium salt, such as diphenyliodonium hexafluorophosphate. An organic solvent also can be used.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
82 words
A method of coating a conducting substrate which comprises using the conducting substrate as the anode in an electrolyzed mixture comprising a cationically polymerizable organic material and 0.1 to 10% by weight, based on the weight of the cationically polymerizable organic material of aryliodonium salt or arylsulfonium salt having an MQ d anion, where M is a metal or metalloid selected from boron, phosphorus, antimony and arsenic, Q is a halogen radical and d is an integer having a value of 4-6.
Claim 2
Independent Claim
82 words
A method of coating a conducting substrate which comprises using the conducting substrate as the anode in an electrolyzed mixture comprising a cationically polymerizable organic material and 0.1 to 10% by weight, based on the weight of the cationically polymerizable organic material of aryliodonium salt or arylsulfonium salt having an MQ d anion, where M is a metal or metalloid selected from boron, phosphorus, antimony and arsenic, Q is a halogen radical and d is an integer having a value of 4-6.
