POLYMERISATION INHIBITOR

摘要

A monomer composition, stabilised against premature polymerisation, comprising: a) an ethylenically unsaturated monomer or mixture of monomers polymerisable by free radical initiation, and b) an effective amount, sufficient to inhibit premature polymerisation of component (a) of a mixture of: i) 1 to 99 % by weight, based on the total weight of components (i) and (ii) of a mixture of at least one aromatic amine and at least one organic acid in a molar ratio of 10:1 to 1:10, and ii) 99 to 1 % by weight based on the total weight of components (i) and (ii) of at least one stable radical compound.
