Popis:	The behaviour of Ca(OH) 2 on styrene-methacrylate polymer dispersion is studied. Ca(OH) 2 interacts with the polymer dispersion leading to precipitation and loss of filmforming ability. X-ray diffraction analysis has shown changes in 17–23 degree (2⊝) area. Heating the mix of Ca(OH) 2 with dispersion after treating with hydrochloric acid leaves a residue. This certainly is CaO which interacted with polymer dispersion and formed a complex. This is due to interaction between divalent calcium ions and carboxylic group in the dispersion leading to cross-linking with no filmforming character.
