In addition, other operation condition, such as soapless seeded preparation schedule or without seed, could meet the requirement of the larger particle sizes, broader particle sizes distribution and lower viscosities. Besides the increment of addition rate induces the peel strength and tack decreased and the holding power increased for the PSA tapes that are made from the multicopolymer latexes, the above operation conditions which lead the particle sizes to enlarge would increase the peel strength and tack, and decrease the holding power.
