Ethylene-norbornene copolymers were synthesized with a homogeneous catalyst system based on bis(imino) pyridine iron with the addition of diethyl zinc (DEZ) as alkyd transfer agent to promote immortal copolymerization. The addition of DEZ did not influence the catalytic activity in copolymerization with 7.5 mmol of norbornene (NB), but in the reactions with 70 mmol, the comonomer promoted an in...

The hydrophobic nature of the alkyd polymer makes them good choices when water repellency is important. However, formulating alkyds into low VOC (volatile organic compound) waterborne coatings results in a number of problems, which can be minimised ...
