End-group characterisation of three functionalised poly(methyl methacrylate) (PMMA) samples was performed by means of matrix-assisted laser desorption/ionisation-mass spectrometry (MALDI-MS). MALDI-time of flight (MALDI-TOF) data were employed to gen

We have studied the polymerization of methyl methacrylate (MMA) using biscyclopentadienylcalcium (Cp2Ca) and bis(pentamethylcyclopentadienyl)calcium (Cp2 *Ca) as initiators. Polymerizations initiated with CP2Ca produced poly(methyl methacrylate), PMM

We have studied the polymerization of methyl methacrylate with cesium and tetramethylammonium salts of diethyl 2-ethylmalonate carbanion. For polymerizations initiated at room temperature, no effort was made to control the exotherm. The polymerizatio

Novel maleimide functionalized oligomers have been prepared by a multistage route involving the reaction of maleic anhydride with hindered primary polyamines derived from the acid catalysed oligomerization of diphenyl ether (DPE) with formaldehyde. M

Novel maleimide functionalized oligomers have been prepared from the acid catalysed co-oligomerization of N -(4-phenoxy)-phenylmaleimide (PPM) with a series of activated aromatics (diphenyl ether (DPE), diphenylmethane (DPM) and dibenzofuran (DBF)) i

Poly(methyl methacrylate) (PMMA) has been exploited as a material for over 60 years. More commonly recognized under trade names such as Lucite, Perspex or Plexiglas, it was originally developed during the 1930s as a safe replacement for glass in airc

Methacrylate-ended poly(dimethylsiloxane) (PDMS) macromers of M n 500, 1160 and 9750 were prepared and copolymerized with styrene to yield three series of graft copolymers comprising PDMS chains on a polystyrene (PS) backbone. The low M n values of t

A novel class of matrix polymer based on amorphous crosslinkable aromatic polyamides has been developed. These polymers possess an attractive combination of good moisture resistance, high glass transition temperature ( T g ) and reasonable toughness.

The synthesis and characterization of methacrylate-ended macromers ( M n 500 to 10 000) and their copolymerization with styrene (M2) is described. The experimental errors in the values of the reactivity ratios r1 render them meaningless. Values of r2

Copolymers of acrylonitrile (M 2 ) and two methacrylate-ended polysiloxane (PDMS) macromers have been prepared and characterized. As in previous investigations, the errors in r 1 render their values meaningless. Values of r 2 could be determined with
