Calculez nr moli brom--> niu= 12g/160g/mol= 0,075mol brom--
--. >0,075 mol copolimer
---> 0,075molcopolimer bromurat daca η=10 0% ===..>0,075x75/100= 0,0562mol daca η= 75%
m= 0,o562molx276,5g/mol=15,55 g copolimer bromurat
m= 0,075mol x54g/mol= 4,05g diena daca η=100%
m= 4,05x100/75= 5,4g diena , o masa mai marepentru ca sunt pierderi
m= 0,075molx62,5g/mol= 4,6875g clorura daca η-100%
m=4,6875x100/75=6,25 g clorura
XCH2=CH-CH=CH2 +YCH2=CHCl= -(CH2-CH=CH-CH2)x--(CH2-CHCl)y-
prin bromurare -(CH2-CHBr-CHBr-CH2)x--(CH2-CHCl)y-
