LADS helped write SKHMU polycondensation of urea and formaldehyde NH2-CO-NH2 + H2C = O ----> r134a NH2-CO-NH-CH2-OH NH2-CO-NH-CH2-OH + NH2-CO-NH2 ---- > NH2-CO-NH-CH2-NH-CO-NH2 + H2O NH2-CO-NH-CH2-NH-CO-NH2 + H2C = O ----> NH2-CO-NH-CH2-NH-CO- NH-CH2-OH NH2-CO-NH-CH2-NH-CO-NH-CH2-OH + NH2-CO-NH2 ----> etc. ... Moreover, similarly comes and reaction of formaldehyde with CO- NH -CH2- groups to form a branched network structures.
Describe the process of producing polypropylene r134a carbonate
Describe the process of producing polypropylene carbonate Propylene - cyclic ether 1,2-propanediol and carbonic acid. Polymerization it is ring opening and formation of linear r134a polyester: ----> [-CH (CH 3) -CH 2 -O-CO-O-] n polymerization catalysts - a Lewis acid (e.g. - BF 3 etherate in a (C 2 H 5) 2 O * BF 3)
