Crystallization of Isotactic Poly(methylmethacrylate) in Monolayers and Thin Films [PDF]

open access: yes, 1991
Langmuir-Blodgett monolayers of isotactic PMMA exhibit a pressure-induced transition upon compression, that can be described in terms of a two-dimensional crystallization process, analogous to a normal melt crystallization.
