The acrylic polymer which offers the best all-round properties for a metal-coating lacquer exposed to the weather, is the hardest acrylic polymer, polymethyl methacrylate (molecular weight 80 000-150 000). It is hard, clear, scarcely coloured, very little affected by ultra-violet light, insoluble in commercial petrols and resistant to acids and alkalis. Marked deviations from the homopolymer reduce one or... 

Acrylic coating polymers n. Acrylic resins or polymers such as polymethyl methacrylate used for formulating coating. 

This technique has found the following applications in addition to those discussed in Sections 10.1 (resin cure studies on phenol urethane compositions) [65], 12.2 (photopolymer studies [66-68]), and 13.3 (phase transitions in PE) [66], Chapter 15 (viscoelastic and rheological properties), and Section 16.4 (heat deflection temperatures) epoxy resin-amine system [67], cured acrylate-terminated unsaturated copolymers [68], PE and PP foam [69], ethylene-propylene-diene terpolymers [70], natural rubbers [71, 72], polyester-based clear coat resins [73], polyvinyl esters and unsaturated polyester resins [74], polyimide-clay nanocomposites [75], polyether sulfone-styrene-acrylonitrile, PS-polymethyl methacrylate (PMMA) blends and PS-polytetrafluoroethylene PMMA copolymers [76], cyanate ester resin-carbon fibre composites [77], polycyanate epoxy resins [78], and styrenic copolymers [79]. 

Mitsubishi Rayon Polymer Nantong Co Ltd, a jv between Mitsubishi Rayon Co (Tokyo, Japan www.mrc.co.jp) and Marubeni Corp (Tokyo, Japan www.marubeni.com), is building a plant to produce acrylic sheet based on polymethyl methacrylate (PMMA). The US 19 million facility has 20 000 tpa of acrylic sheet capacity and 3500 tpa of acrylic coating resins for the paint industry. Completion is due in the spring of 2005.
