A new method for generating and modeling reduced‐scale copolymer gradients by CVD is reported. By exploiting diffusion through confined channels, functionalized [2.2]paracyclophanes are copolymerized into their poly (p‐xylylene) (PPX) analogues as a composition gradient. Fourier transform infrared (FTIR) and X‐ray photoelectron spectroscopy (XPS) are used to verify the gradient composition profiles. Gradients are deposited on both flat substrates and 3‐dimensional cylinders. Both the thickness and compositional profiles are fitted to a diffusion‐based model using realistic physical parameters. The derived equation can be generalized and optimized for any copolymerization gradient through a confined geometry, thus allowing for broad applicability to other copolymer systems.
