    • Actually we should consider here slightly different process: two smaller clusters combining into a chosen M-cluster. However the rates of the two processes are of the same order of magnitude.

    • This statement is true for treelike clusters which are formed in the classical gelation regime considered here. In the critical (percolation) regime, i.e., in a close vicinity to the gel point, the cluster structure is more complicated. In particular, clusters might include closed cycles (loops) of connected chains. In this regime the fraction of red bonds is lower than in the classical gelation regime. The percolation regime is considered in section 4.3. We are grateful to the reviewer who commented on this point.

    • The scaling law, eq 3.13, is valid up to logarithmic corrections which are entirely neglected here and below.

    • 1 = 1 - p*, where p* is the fraction of all closed stickers defined by eq 5.1. Although this method leads to the same result, eq 4.2, it is less preferable since applicability of eq 5.1 in the regime where p* is dominated by local pairs is not obvious.
