ABSTRACT:
A process for the manufacture of copolymers of ethylene with tert-butyl acrylate and acrylic acid at from 200.degree. to 350.degree. C under pressures above 800 atmospheres using mean residence times of up to at most 100 seconds, in which the reaction mixture obtained from the polymerization is kept for from 2 to 10 minutes at from 200.degree. to 250.degree. C under a pressure of not more than 500 atmospheres. Terpolymers are obtained which may be used as hot-melt adhesives in the form of thin and extremely homogeneous films.
