Abstract
The invention concerns copolymers of propylene and but-1-ene in which the proportion of units derived from but-1-ene is from 10 to 40% by weight and the proportion of isolated ethyl branches which they contain is at least equal to the square of the proportion [P] of units derived from propylene contained in said copolymers. The copolymers of the invention can be used for the production of heat-sealable films.
