Poly(Alkyl Alpha-Bromoacrylates). 2. Preparation And Properties Of The Methyl, Ethyl, N-Propyl, Isopropyl, N-Butyl, And N-Pentyl Esters Of Varied Tacticity, William Macknight, K. G. Saunders, R. W. Lenz Dec 1981

William MacKnight

Polymers of widely ranging t.acticities, from highly isot.actic to highly syndiotactic, were synthesized from methyl, ethyl, n-propyl, iaopropyl, n-butyl, and n-pentyl a-bromoacrylates. The iaotactic polymers were synthesized with a modified Grignard complex consisting of the reaction product between a Grignard reagent and benzalacetophenone. A low-temperature, photolytically induced, free radical polymerization reaction was employed for the preparation of the syndiotactic polymers. Only atactic poly(tert-butyl a-bromoacrylate) could be synthesized because of its failure to polymerize with the modified Grignard complex or at temperatures below -20 °C. Polymer tacticity was determined by 19-MHz 13C NMR spectroscopy. Complete assignment.a for the ten pent.ad peaks …

Small-Angle Neutron Scattering From Polypentenamer Sulfonate Ionomers, William Macknight, T. R. Earnest Jr., Julia S. Higgins Dec 1981

Small-Angle Neutron Scattering From Polypentenamer Sulfonate Ionomers, William Macknight, T. R. Earnest Jr., Julia S. Higgins

William MacKnight

The physical structure of polypent.enamer suHonat.e ionomers has been investigat.ed by small-angle neutron scatt.ering (SANS) and small-angle X-ray scatt.ering (SAXS). For a 17% cesium salt, a SAXS peak is observed in the dry stat.e at a value of the scatt.ering vector Q = 0.18, but this ionomer peak is undet.ectable by SANS. The addition of several wat.er molecules per salt group affords adequat.e neutron scatt.ering contrast to identify a scatt.ering maximum corresponding to the X-ray peak. SANS maxima are also observed in swollen 5.8% and 12% polypent.enamer ionomers as well as in hydrogenated ionomers. Higher wat.er cont.ents appear to effect …
