CH3-CO-CH3 + HCN ⇒ (CH3)2C(OH)-CN + H2O ⇒( CH3)2C(OH)-COOH ⇒
CH2=CH(CH3)-COOH + CH3OH ⇒ CH2=CH(CH3)-COOCH3
n CH2= C(CH3)- COOCH3⇒-[CH2-(CH3)C(COOCH3)-]n-
n acrilat de metil = n acetona = 0,8·551/58 = 7,6kmoli
teoretic : m polimer = m monomer = 7,6·100 = 760kg
m material plastic = 760·100/95 = 800kg
