Oswald, Iain and Urquhart, Andrew (2011) Polymorphism and polymerisation of acrylic and methacrylic acid at high pressure. CrystEngComm, 13 (14). pp. 4503-4507. ISSN 1466-8033
The polymorphism and polymerisation of two related acids have been investigated under high pressure conditions. Acrylic acid crystallises as a new polymorph at 0.65 GPa whilst methacrylic acid crystallises in a new polymorph at a higher pressure of 1.5 GPa. Both these new polymorphs exhibit similar hydrogen bonding motifs to the low temperature phases, however, the molecular packing differs significantly.
