The poly(vinylpyridine) and poly(tert-butyl methacrylate) copolymers can easily be converted to either cationic or anionic polyelectrolytes by protonation of the pyridine rings or by base hydrolysis of the tert-butyl ester units, respectively. The highly branched structure of the molecules, in combination with the polyelectrolyte effect, should confer useful properties to these materials in solution for applications such as pH-sensitive reversible gels. [Pg.224]

Figures 6 and 7 illustrate the preposed mechanism in OC. Using the specific example of a separation of a styrene n-butyl methacrylate copolymer, the first SEC separates the copolymer according to molecular size in solution. At any desired retention time, the flow in the first instrument is stopped and an injection made into the second instrument of a single molecular size "slice" of the chrcoiatogram. The solvent running in the second instrument is a mixture of tetrahydrofuran (THF) and n-heptane. THF is a solvent for both styrene cuid n-butyl methacrylate portions of the polymer molecules. However, n-heptane is a nonsolvent for the styrene-rich portions. As a result, vrfien the injection is made into the second instrument, the styrene-rich molecules will shrink relative to the n-butyl methacrylate-rich molecules. An immediate size distribution will be present vrfiich will reflect the composition differences. The smaller styrene-rich molecules will enter more pores of the column packing than their n-butyl methacrylate-rich counterparts and so be fractionated. Furthermore, since the styrene-rich molecules "hate" the mobile phase, they should find the surface area of the packing more "sticky" than the n-butyl methacrylate-rich molecules. Thus, again the styrene-rich molecules should be retarded relative to the others. According to this picture, the mechanisms of size exclusion, adsorption and partition are thus able to act synergistic ally to accomplish a composition separation.

Hydrogen bonding between the solvent and acrylic acid/butyl methacrylate copolymer led to better adherence of the dried films than when H bonding was absent. The effect was absent in the case of poly(butyl methacrylate). [Pg.148]

Of the reported materials, the only commercially available resists are one of the MMA-MAA/MMA-MACl compositions and a t-butyl methacrylate copolymer material (13). In this work, we have chosen to examine the copolymer mixture, which crosslinks at a temperature of 160°C compared to 250 C for the single copolymer. We have carried out experiments to optimize its use for direct write electron beam lithography. [Pg.87]

Samples tested were styrene copolymers of methacrylates, acrylates, vinyl acetate, and acrylonitrile, in addition to ethyl methacrylate-butyl methacrylate copolymers. These samples were dissolved in the initial mobile phase and the injection volume was 0.05-0.2 mL. These samples were prepared by solution polymerization at low conversion and have rather narrow CCD. These samples are random (statistical) copolymers. [Pg.215]

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. [Pg.219]

The C=0 carbon spectrum of MMA and butyl methacrylate copolymer exhibits similar spectral features, that is, splittings due to both monomer sequence and stereosequence,213 214 although the signal assignments for the 25-MHz 13C NMR spectra based on only monomer sequence distribution215 had been made erroneously. [Pg.162]

Amrani and co-workers [48] have used fluorescence measurements of energy transfer from donor to acceptor for studies of polymer compatibility. They labelled methyl methacrylate-ethyl methacrylate copolymer and/or methyl methacrylate-butyl methacrylate copolymer with donor-naphthalene and polymethyl methacrylate with acceptor-anthracene. The variation in the ratio of donor to acceptor fluorescence was plotted as a function of butyl methacrylate and ethyl methacrylate in the copolymer and gradual increase of the ratio corresponded to gradual transition from two-phase to a one-phase system. The fluorescence technique was found to be more sensitive to small changes of compatibility of the polymers. [Pg.121]
