Decyl methacrylate

Among the pairs of monomers used in synthesizing block copolymers by this method are MMA/AN, C2F4/ MMA, and HEMA/DMA (HEMA = hydroxyethyl methacrylate and DMA = decyl methacrylate). 

Chain degradation in turbulent flow has been frequently reported in conjunction with drag reduction and in simple shear flow at high Reynolds numbers [187], Using poly(decyl methacrylate) under conditions of turbulent flow in a capillary tube, Muller and Klein observed that the hydrodynamic volume, [r ] M, is the determining factor for the degradation rate in various solvents and at various polymer concentrations [188], The initial MWD of the polymers used in their experiments are, however, too broad (Mw/Iiln = 5 ) to allow for a precise... 

Several examples of ion-selective electrodes with ionophores covalently attached to a self-plasticized polymeric matrix have been reported in the literature. For instance, a Ca-selective electrode with the ionophore attached to a methylmethacrylate-co-decyl methacrylate backbone was developed recently [91]. Ion exchangers such as the dodecacarborane anion have been anchored to the polymeric backbone, with grafted dodecarborane showing greatly improved retention in the polymeric phase [88],...

Anderson et al. [59, 75,76] have been pursuing their extensive researches on the biomedical behavior of PEUUs having various formulations modified with hydrophobic acrylate (or methacrylate) polymer or copolymer additives. The most distinguished additive was Methacrol 2138F, which is a copolymer between diisopropylaminoethyl methacrylate and decyl methacrylate [co(DIPAM/DM)] (in a 3-to-l ratio). The protein adsorption assay showed that PEUU (Biomer-type) films loaded or coated with Methacrol or poIy(DIPAM) adsorbed significantly lower amounts of human blood proteins (Fb, IgG, factor VIII, Hageman factor and Alb) than the base PEUU or PEUUs modified by other additives. It was revealed from their experiments that poly(DIPAM) as well as Methacrol exhibited a prominent suppressing effect on the protein adsorption process. 

Monomers with relative reaction rates well below 1 (methacrylo-nitrile and decyl methacrylate). 

Decyl methacrylate (Figure 13) shows only one broad maximum. The reproducibility of the curve at high conversions was much lower than usual. This is partly caused by the low reaction rates in this range. The reaction time was approximately 40 hours at a dose rate of 1920 rads per hour.

Solid-state ISEs with conducting polymers are also promising for low-concentration measurements [60,63,74], even below nanomolar concentrations [60,74], which gives rise to optimism concerning future applications of such electrodes. In principle, the detection limit can be improved by reducing the flux of primary ions from the ion-selective membrane (or conducting polymer) to the sample solution, e.g., via com-plexation of primary ions in the solid-contact material. For example, a solid-state Pb2+-ISEs with poly(3-octylthiophene) as ion-to-electron transducer coated with an ion-selective membrane based on poly(methyl methacrylate)/poly(decyl methacrylate) was found to show detection limits in the subnanomolar range and a faster response at low concentrations than the liquid-contact ISE [74].

As was found for electrochemical-based sensors, problems can occur with peeling of the membrane element from its substrate. PVC is not the only membrane used for optrodes other polymers include polyurethane, which displayed improved adhesion [125]. Ambrose and Meyerhoff [126] incorporated ion-selective species into thin liquid films of decyl methacrylate on glass and then photopolymerised the methacrylate, with simultaneous crosslinking and covalent attachment of the polymer to its substrate to give substantially improved lifetimes. 

For demonstration, the SEC behavior of different polymethacrylates is given in Fig. 6. On silica gel as the stationary phase and methyl ethyl ketone as the eluent, all polymethacrylates elute in the SEC mode. The calibration curves of elution volume vs. molar mass for poly(methyl methacrylate) (PMMA), poly(ferf-butyl methacrylate) (PtBMA), poly( -butyl methacrylate) (PnBMA) and po-ly(decyl methacrylate) (PDMA) reflect the inability of the system to separate dif-... 

Besides the overall composition of blends and random copolymers, valuable information can be obtained in the case of block copolymers. If a block copolymer contains a homopolymer fraction, a shoulder or second maximum in the MMD curve can be obtained that should have a different chemical composition. Figure 9 shows the MMD of a block copolymer of methyl methacrylate and decyl methacrylate, in which a second lower molar mass maximum can be identified as poly(decyl methacrylate) (PDMA) by dual detection [37]. The increase in the PDMA content with molar mass in the main fraction is reasonable and corresponds well with what is expected from the synthesis. It is worth noticing that this type of information can only be obtained by the D-RI detector combination, because both PDMA and PMMA have a similar low response in UV.

Hummel et al. (1967) also conducted brief studies of a number of other monomers. Chloroprene behaved simibrly to styrene. Methacrylonitrile behaved somewhat like methyl methacrylate with a definite gel effect. Butyl methacrylate behaved somewhat like styrene but with two small maxima in the rate-conversion curves tbc reasons for this arc unknown but the second small peak could arise from the gel effect. Decyl methacrylate showed only one maximum rate at about 50% conversion. Again the reasons for this behavior are unclear. Isoprene did not polymerize in emulsion at either low or high dose rates. Kaly in et al. (197S) have presented a study of the radiatiorr-induced polymerization of vinyl fiuoride in emulsion.
