 '''Acrylonitrile styrene acrylate (ASA)''' has great toughness and rigidity, good chemical resistance and thermal stability, outstanding resistance to weather, aging and yellowing and high gloss.
-'''ASA''' possesses a similar chemical structure to ABS, since both consist of a SAN matrix containing a graft rubber. However, while the core of the graft rubber of ABS consist of polybutadiene, that of ASA consists of poly(n-butyl acrylate), and this accounts for important differences in the properties of the two plastics.

 __NOTOC__
-'''Acrylonitrile-styrene-acrylate''' is the predecessor of ABS (Acrylonitrile- butadiene-styrene). Rigid transparent material, resistant to thermal shock and has a good chemical resistance.
+'''Acrylonitrile-styrene-acrylate''' is the predecessor of ABS (Acrylonitrile- butadiene-styrene). ASA is an acrylate rubber modified styrene acrylonitrile copolymer with an acrylate rubber modifier included at the polymerisation stage. Developed to create similar material as ABS but superior in terms of weather resistance.

 ASA polymers are produced by introducing a grafted acrylic ester elastomer during the copolymerization reaction between styrene and acrylonitrile.
