I would like to use environmentally benign solvents for dissolution of PMMA to make thin films and coatings.

A method to produce thin layer of PMMA (poly (methyl methacrylate) films by spin coating is reported. PMMA is dissolved in xylene, a mixture of MIBK-xylene and chloroform. Varying the PMMA concentration and spin-coating speeds controls the thickness of the PMMA films. Using chloroform as solvent evidenced thickness around 10 μm. This thickness is suitable for core of optical polymeric films. These PMMA films with lower roughness are treated with CHF3 plasma to produce the cladding. The morphology of PMMA films is analyzed by atomic force microscopy and scanning electron microscopy. Profilometry, metricon and contact angle analysis are associated with the effective parameters in roughness and their effect before and after plasma treatment. Gel permeation chromatography (GPC) is used for estimating molecular weights of PMMA.
According the following study :

the best solvents compatibles with PMMA are :
CH2Cl2/CH3NO2; CHOOCH3/CH3NO2; CHOOCH2CH3/CH3NO2; CH3COOCH3/CH3NO2; CH3COOCH2CH3/CH3NO2; CH3COOCH3/C3H7NO; CH3COOCH2CH3/C3H7NO and CH3COO(CH2)3CH3 /C3H7NO.
