    Notes: Abstract It can be predicted that, provided the interfacial energies are well chosen for two individual particles, then it is possible to engulf one particle into the other. This has now been achieved experimentally using poly-[butylmethacrylate] particles as the host material and poly-[styrene] particles for engulfment. Initially, anionic poly-[styrene] particles were heterocoagulated onto electrosterically stabilised cationic particles of poly-[butylmethacrylate]. Then on heating the heterocoagulated units above the glass transition temperature of the latter engulfment occurred.

    Preparation of core-shell polymer colloid particles by encapsulation (1997)
    Springer
    Colloid & polymer science 275 (1997), S. 274-283

    ISSN: 1435-1536

    Notes: Abstract  By means of heterocoagulation anionic poly-[styrene] particles were coated with smaller electrosterically stabilised cationic particles of poly-[butyl methacrylate]. On heating the heterocoagulated units 45 °C above the glass transition temperature of poly-[butyl methacrylate], as predicted theoretically, the latter polymer spread over the surface of the poly-[styrene] particle to give a composite particle with a core-shell structure. It was found that the extent of packing of the small particles on the larger core particle was a critical feature of the coating process.

    Behavioural effects of the nicotinic agonists N-(3-pyridylmethyl)pyrrolidine and isoarecolone in rats (1990)

    Notes: Abstract The nicotinic agonists N-(3-pyridylmethyl)pyrrolidine (PMP) and isoarecolone have been compared with (−)-nicotine in three behavioural procedures and as inhibitors of [3H]-(−)-nicotine binding. Locomotor activity was recorded as movements between beams of infra-red light (ambulation). In experimentally naive rats, nicotine, PMP and isoarecolone reduced ambulation. In rats receiving nicotine chronically and previously exposed to the activity cages, nicotine and PMP increased ambulation in a dose-related manner. However, isoarecolone did not increase ambulation at doses that were active in other procedures. In rats trained to discriminate nicotine from saline in a two-bar operant conditioning procedure with food reinforcement, there was full generalization to PMP. It was also found that PMP potently inhibited the binding of [3H]-(−)-nicotine to rat brain membranes in vitro. These results were discussed with previous data for the discriminative stimulus and ligand-binding effects of isoarecolone obtained under similar conditions. The relative potency of PMP in different behavioural procedures was similar to that of (−)-nicotine. However, isoarecolone was relatively 10 times more potent in decreasing ambulation than would have been expected from its potency in the ligand-binding and discriminative stimulus procedures. The results suggest that the pharmacodynamic action of isoarecolone differs from that of nicotine and PMP, and that it will be a useful probe in further analyses of central nicotinic mechanisms.

    Study of (π-C5H5)2Ti(CH3)Cl and (π-C5H5)2Ti(C6H5)Cl in soluble Ziegler catalysts (1972)

    Notes: Soluble ethylene polymerization catalysts derived from (π-C5H5)2Ti(R)Cl and R ′AlCl2, where R = methyl or phenyl and R ′ = methyl or ethyl, were studied both by polymerization kinetics at 0°C and by diagnostic experiments. It was found that the first insertion of ethylene into the Ti—R bond is difficult when R = methyl or phenyl, and for this reason these catalysts show a different overall behavior than when R = ethyl or higher alkyl.

    Notes: Soluble ethylene polymerization catalysts derived from (π-C5H5)2Ti(R)Cl and R′AlCl2 where R is ethyl or higher alkyl and R′ may be methyl or ethyl, were studied both by polymerization kinetics at 0°C and by diagnostic experiments. An early acceleration in rate occurred at this temperature in toluene solvent which was due to a solvent dependent increase in catalyst activity, not to a gradual formation of catalyst. No such solvent effect was found in nonaromatic solvents. The subsequent decay in rate, at least at low temperatures, did not depend upon valence reduction. The effect of Al/Ti ratio was studied, and certain discrepancies in the literature were shown to be due to the method of making kinetic measurements. Oxygen, which has previously been reported to affect the polymerization rate with these catalysts, was also found to eliminate the acceleration period in toluene when present in the amount of 1% of the catalyst. These catalysts gave polymers at low temperature for which the active site had long life and which did not undergo chain transfer. Therefore, they approximate many of the characteristics of living polymers.
