The presence of the pendant methyl (CH3) groups prevents the polymer chains from packing closely in a crystalline fashion and from rotating freely around the carbon-carbon bonds.
The number of ALD publications was increasing, and alkyls and -diketonates were used as reactants to generate new deposition processes for semiconductors [, In 1990, Markku Leskel suggested changing the name ALE to ALD, at the International Symposium on Atomic Layer Epitaxy [, Currently, ALD is mostly applied in microelectronics field, such as transistors, capacitors, energy storage, conversion, biomimetic membranes, and graphene for desalination supports, catalysts, and medical applications [, PMMA surface engineering opens new opportunities to modify the polymer surface chemistry to attain improved properties with a second material. or you can just click on the image itself.

ICI registered the product under the trademark Perspex. Nature doesn't like that arrangement very much, so the chain twists to relieve the "steric strain" also called "steric interaction." However, PMMA presents a challenge for ALD due to its lack of active surface sites, necessary for gas precursor reaction, nucleation, and subsequent growth. Sinha, A.; Hess, D.W.; Henderson, C.L.
