Watanabe62) studied systematically the copolymerization of ra-methacryloyl-polyoxyethylenes, with monomers such as acrylonitrile, styrene, butyl methacrylate, and methacrylic acid. It should be mentioned that the macromonomers that he prepared are very short so that no difficulties were encountered to isolate the graft copolymers formed. There are many applications for these graft copolymers, e.g. as additives in polyacrylonitrile films and fibers they cause improved antistatic properties. They have been tested as varnishes, coatings, and wood dimensional stabilization agents.

Plots of the relationship between the styrene content and retention volume for copolymers of styrene-acrylate and styrene-methacrylate with the same ester group lay roughly on the same line. This result indicates that a pair of copolymers with the same ester group and the same styrene content could not be separated (24), For example, copolymers of styrene-methyl acrylate and styrene-MMA with the same styrene content cannot be separated by this technique. In copolymers with the same styrene content, styrene-butyl acrylate and styrene-butyl methacrylate copolymers eluted first from a column, the copolymers of ethyl esters were next, and those of methyl esters eluted last.

Zimina et al. [753] studied PMMA co-polymers and poly(styrene//-butyl methacrylate) (PtBMA) co-polymers on a 300 A silica column under critical conditions —conditions in which one component of an A-B block co-polymer is eluted whereas the alternate components have no effect on its elution. PMMA polymers with molecular weights of 27,700, 60,000, and 107,000 were chromato-gn hed under critical (57.0/43.0 DCM/acetonitrile) and near-critical (57.2/42.8, 56.9/43.1 and 56.7/43.3 DCM/acetonitrile) conditions. In those separations on either side of the critical condition where near-critical conditions were used, peak shape and elution order changed dramatically. A 1 pL injection of 0.1% w/v standards was used. Similar results were obtained for an 80,000 MW PtBMA copolymer where critical conditions occurred at a mobile phase consisting of 90.7/9.3 DCM/acetonitrile.

Interestingly, alkyl radicals can be generated along the polymer backbone in the presence of monomer and nitroxide via a bimolecular process. The preparation of polypropylene (PP) functionalized by hydroperoxide by means of y-irradiation was reported. The resulting macroperoxide was then heated up to 125 °C in the presence of styrene or a styrene/butyl methacrylate mixture to produce the desired PP-g-PS or PP-g-P(S-co-BMA), respectively. Daly et a . and Daly and Evenson used esters of N-hydroxypyridine-2-thione or Barton esters to produce radicals on a polymer backbone under UV irradiation. This was successfully applied to poly (arylene ether sulfone) or hydroxypropyl cellulose backbones. ...

Star block copolymers in which each branch is an amphiphilic star block copol)nners can be obtained in a similar way. The polymerization of the second monomer can be initiated by the carbanions of the first one, that is, in the order of increasing electroaffinity. Typical examples include styrene/butyl methacrylate [75] and styrene/vinylpyridine [76].
