摘要： The present application relates to processes for producing linear polyvinylpyridines without the use of hazardous solvents, and in a manner that allows control over the rate of heat generated by the reaction and the temperature of the reactor vessel. The processes involve the use of an initiator to initiate polymerization of vinylpyridine monomers in water. Processes of the invention provide good reaction rates and conversions, and are particularly advantageous in achieving control of the molecular weights of the final product polymers.

摘要： A method for producing polymerisable solution which comprises dissolving an ethylenically unsaturated zwitterionic monomer in a co-monomer system comprising a functionalised ethylenically unsaturated monomer in which the zwitterionic monomer is soluble, a siloxane group-containing monomer or macromer, and a crosslinking agent is disclosed. The polymerisable solution is biocompatible and can be used to produce polymers and articles such as contact lenses.
