    Notes: Summary The title monomer was synthesized from the corresponding aldehyde via a Wittig reaction. The monomer was polymerized using free radical initiation and its high field 1H- and 13C-NMR spectra were recorded. When analyzed in terms of stereochemistry the spectra showed poly(6-vinyl-1,4-benzodioxane) is an atactic polymer when synthesized via free radical initiation.

    Notes: Summary The title vinyl thiophene monomer was synthesized by dehydration of the corresponding secondary alcohol. Free radical initiated copolymerizations with methyl methacrylate, styrene or isobutyl methacrylate were performed and the copolymer compositions were used in the calculation of reactivity ratios. The data was analyzed via a nonlinear least squares error-in-variables method. The 2,5-dimethyl-3-vinylthiophene was shown to have equal or slightly less reactivity than each of the monomers chosen as comonomers.

    Cationic oligomerization of 3-methylene-p-menth-4(8)-ene and 2-methyl-3-methylene-5-isopropylbicyclo [3.1.01,5] hexane (1995)

    Notes: Summary The title monomers were synthesized via Wittig reaction from thujone and pugelone. The monomers were found to react rapidly with cationic initiators at temperatures from -15° to 22°C. The products of these reactions were found to be low molecular weight oligomers. The reaction temperature, presence of solvent or initiator type and concentration seemed to have some effect on the molecular weights of the products obtained.

    Copolymerization of N-vinyl phthalamide with acrylate and methacrylate monomers and preliminary analysis of the stereochemistry of poly(N-vinyl phthalamide) (1995)

    Notes: Summary N-Vinyl phthalamide was copolymerized with methyl methacrylate, isobutyl methacrylate or butyl acrylate. The copolymerizations were initiated free radically and it was necessary to conduct the polymerizations in solution or else insoluble products would result. In most cases the polymerizations preceded to relatively high conversions in a short time. The conversions necessitated the use of high conversion methods to calculate the reactivity ratios. The N-vinyl phthalamide was found to be the less reactive monomer in all cases. As part of this study, poly(N-vinyl phthalamide) homopolymer was synthesized by free radical initiation. While the 1H-NMR spectrum yield very little information concerning polymer stereochemistry, the methine carbon resonance in the 13C-NMR spectrum displayed a sensitivity to polymer stereochemistry.

    Analysis of the 1H-NMR and 13C-NMR spectra of poly(3-methyl-1-vinylpyrazole) (1995)

    Notes: Summary The title monomer was polymerized in solution via free radical initiation. The polymer's 300 MHz 1H-NMR and 75.5 MHz 13C-NMR spectra were recorded and analyzed in terms of polymer stereochemistry. Most of the resonances in both the 1H-NMR and 13C-NMR spectra showed multiplicity consistent with sensitivity to polymer stereochemistry. However the 13C-NMR spectrum proved somewhat easier to interpret. The analysis of both the 1H-NMR and 13C-NMR spectra very strongly indicate that poly(3-methyl-1-vinylpyrazole) is an atactic polymer.

    Notes: Summary The title monomer was synthesized and polymerized using free radical initiation. The polymerization was facile and proceeded rapidly to high conversion. The high field 13C-NMR and 1H-NMR spectra of the polymer had several signals that displayed sensitivity to polymer stereochemistry. Analysis of these signals showed poly(2,5-dimethyl-3-vinyl thiophene) to be an atactic polymer.

    Notes: Summary A low molecular weight coumarone (or 2,3-benzofuran)-indene resin was converted to a β-ketoester functional material by Friedel-Crafts acylation with acetyl chloride, reduction to a secondary alcohol and reaction with t-butyl acetoacetate. Each reaction was essentially quantitative as shown by spectroscopy and elemental analysis. The final product proved to be crosslinkable at ambient or elevated temperature by the addition of multifunctional amines.

Analysis of these resonances showed that the polymer had an atactic sterochemistry.
