A system involving homopolymerisation of a 3‐functional monomer has been studied by using an off‐lattice long‐range percolation model. The elementary reaction steps were controlled by substitution effects and by local concentrations of units. The latter were controlled by setting a constant value to a range‐of‐reaction parameter called the capture radius. The critical conversion at gelation in the system turned to the classical one as the value of capture radius increased.
