When cyclohexyl methacrylate (CHMA) is an ester of methacrylic acid . It contains a cycloaliphatic ring and an unsaturated double bond . It is generally used as a monomer for different classes of binders .

properties

When used in polymers that are used as paint binders , cyclohexyl methacrylate combines two actually opposing properties: CHMA has a high glass transition temperature , but has little effect on increasing the solution viscosities . The reason for this is the relatively compact structure of the monomer . Other monomers with these properties would be, for example, tert -butyl acrylate , tert- butylcyclohexyl acrylate or also isobornyl methacrylate . The heat of polymerization is −51 kJ mol ⁻¹ or −303 kJ kg ⁻¹ . Cyclohexyl methacrylate forms flammable vapor-air mixtures. The compound has a flash point of 82 ° C.

use

Cyclohexyl methacrylate can be incorporated into binders such as polyacrylates via free-radical or ionic polymerization .
