Other agents include foaming agents, flocculating agents, conditioning agents (activators, vulcanizing agents, pH adjusting agents, etc.), and the classifications thereof and their exemplifications are shown in Table 1. The results of the examples are shown in Table 2, the following figure and Table 3.
