Alkyl group carbon chain length and density strongly affect the mechanical reinforcement of functional ized MWCNTs.
The interaction between butyl group of n-butyl methacrylate and alkyl group of alkyl acrylate increases with an increase in the number of carbon atoms in alkyl acrylate monomer and destabilizes the copolymer because of steric hindrance because it creates higher chain stretching or larger hydrodynamic radius in solution.

BASF Corporation has been granted a patent for a method of making a curable coating composition containing a carbamate functional reactive additive, providing a compound comprising at least one epoxy group and at least one branched alkyl group of from five to 30 carbon atoms, reacting the compound with carbon dioxide so as to produce a carbonate functional compound, reacting said carbonate functional compound with ammonia so as to produce a carbamate functional reactive additive, and incorporating the carbamate functional reactive additive into a curable coating composition.
The use of DEM-M having a C = C group afforded merely a microcomposite, probably because of the lack of a bulky alkyl group.
