A process for the continuous solution polymerization including the step of polymerizing a first olefin monomer of formula CH2═CHR1, wherein R1 is hydrogen or a hydrocarbon radical having from 1 to 8 carbon atoms with a second olefin monomer of formula CH2═CHR2, wherein R2 is a hydrocarbon radical having from 3 to 8 carbon atoms, in the presence of a polymerization catalyst and in the absence of an inert solvent, at a polymerization temperature (Tp) satisfying the following relationship: Tp≥Tm+20° C. wherein Tm is the melting temperature of the obtained polymer.
