The pressure-assisted photopolymerization in the fullerene complex $\{\operatorname{Cd}(\operatorname{dedtc})_2\}_2\cdot\mathrm{C}_{60}$ (fullerene complex with cadmium diethyldithiocarbamate) observed in the pressure region between $2.24$ and $5.99$ GPa was studied in detail. After a phase transition near $\sim2$ GPa, the Raman spectra exhibit time-dependent changes under prolonged laser illumination regarding the appearance of new peaks in the frequency region of the $A_g(2)$ mode of the $\mathrm{C}_{60}$ monomer. These peaks are related to the fullerene oligomers with a different number of $sp^3$-like coordinated carbon atoms per molecular cage. The polymer content increases with the laser power density and exposure time, while for a fixed laser power, its saturated value is independent of pressure. Outside the pressure range $2.24$ – $5.99$ GPa, photopolymerization is suppressed.
