    摘要： A means for stabilizing a deproteinized natural rubber latex is disclosed, comprising adding a stabilizer selected from the group consisting of (a) an anionic surfactant, (b) an amphoteric surfactant, (c) a nonionic surfactant, (d) a nonionic or amphoteric oligomer or polymer, and (e) an anionic oligomer or polymer. By adding the stabilizer, the mechanical stability of a deproteinized natural rubber latex can be markedly improved.

    摘要： The biocidal effect of a biocide can be enhanced with the use of an effective amount of a biocide activator having the formula (I):

       wherein at least one of R¹, R², and R³ represents a straight-chain or branched alkyl or alkenyl group having 8 to 30 carbon atoms while other(s) represent a group or a combination selected from among -CH₃, -CH₂CH₃,

    and

    groups (wherein n ranges from 1 to 5;
    R⁴ represents a -CH₃ or -CH₂CH₃ group; and
    a counter ion X ⊖ is an anion residue of an acid of an anionic oligomer or polymer having an average molecular weight of from 300 to 20,000.
