| titleOfInvention | Polycationic block copolymers |
| abstract | Block copolymers of the formula:n wherein: n R₁, R₂, R₃, R₄, R₅, R₆, R₇, and R₈ may be the same or different and are generally selected from the group consisting of C₁-C₃ alkyl, C₁-C₃ hydroxyalkyl, or polyoxyalkylene; n D is a halide ion; n L is a linkage derived from a dihalide, x and y are integers ranging from 1-100 and Q is either non-existent or is (BL) y where the bonds between L and A or B are carbon-nitrogen bonds formed by quaternization of the tertiary amine functions of A and B by the organic dihalides from which L is derived which are obtained by first forming a block of units by reacting a monomer of the formula IIn wherein each of R₅, R₆, R₇, and R₈ may be the same or different and is selected from the group consisting of C 1-3 alkyl, C 1-3 hydroxy alkyl and polyoxyalkylene, n m is an integer from 0 to 34 and n r and s are the same or different and are integers from 1 to 6, n with a molar excess of a dihalide of the formula n Hal - L - Hal nwherein Hal represents a halogen atom and L is selected from n -CH₂CH₂-O-CH₂CH₂-, -CH₂CH₂-O-CH₂CH₂-O-CH₂CH₂-, -(CH₂) t - and -CH₂CHOHCH₂- where t is an integer from 2 to 6 and thereafter reacting the product so formed with a compound of the formula IIIn wherein R₁, R₂, R₃, and R₄, are each individually selected from the group consisting of C 1-3 alkyl, C 1-3 hydroxyalkyl and polyoxyalkylene and p, and q are each individually integers of from 1 to 6 and, if necessary, in order to ensure a total molar ratio of compounds of Formulae II and III to those of the formula Hal - L - Hal of 1:1, reacting the product with further compound of the formula Hal - L - Hal are of use inter alia as antistatic agents in detergent formulations and as flocculating agents. |
