Meanwhile, ammonolysis reaction of DPrC is reversible, so it is economical to obtain slow/ controlled released fertilizer by increasing molar weight of urea.
Also disclosed is a method for producing the acetoacetyl polymer, wherein the method is characterised by comprising the following steps: ammonolysing an acetoacetatc via ester ammonolysis reaction using an ami no-containing polysiloxane, and/or esterifyinga hydroxyalkyl-containing polysiloxane via transesterification reaction using an acetoacetate.
Many recycling plants have already practiced chemical modification technologies (hydrolysis, methanolysis and ammonolysis) for polycondensation polymers such as PET and polyurethane; pyrolysis, gasification, catalytic cracking, hydrogenation, coking and visbreaking for polyolefins, PS and PVC [1].
