Cyclohexyl Methacrylate (CHMA)

Cyclohexyl Methacrylate (CHMA) is an ester of Methacrylic acid and is used as a raw material component in the synthesis of polymers. The ester is a monofunctional monomer consisting of a methacrylate group with a characteristic high reactivity and a cyclic hydrophobic group. It forms homopolymers and copolymers which can be obtained from acrylic acid and its salts, amides, and esters, etc.

Cyclohexyl Methacrylate (CHMA) is a very useful starting material for chemical synthesis since it easily undergoes addition reactions with a wide range of organic and inorganic compounds.

In order to prevent polymerisation, Cyclohexyl Methacrylate (CHMA) must always be stored under air, and never under inert gases. The presence of oxygen is required for the stabiliser to function effectively. It has to contain a stabiliser and the storage temperature must not exceed 35 °C. Under these conditions, the storage stability of one year can be expected upon delivery. In order to minimize the likelihood of over storage, the storage procedure should strictly follow the “first-in-first-out” principle. For extended storage periods over 4 weeks, it is advisable to replenish the dissolved oxygen content. If Cyclohexyl Methacrylate (CHMA) is crystallized the product should never be partially molten and taken because of the possible separation from the stabiliser. Ensure that there is no crystallised product in the container before use. Obtain information from supplier/manufacturer before dissolving totally or partially crystallised products. The ambient temperature of the container may not exceed the stated temperature limit when melting the product or keeping it at a moderate temperature.The preferred construction material for tanks and pipes is stainless steel. Carbon steel is also acceptable, although the formation of rust may be a problem with product quality (color). Iron(III)-ions have been shown to be a weak polymerisation initiator. If carbon steel is to be used, special procedures should be used to prepare the tank for use. Storage tanks, pumps, and pipes should be earthed.
