    Notes: Abstract Mandibular resection for oral cancers has significant aesthetic and functional sequelae. A reliable preoperative predictor of mandibular invasion is required to guide the need for and extent of mandibular resection. An orthopantomogram of the mandible is an accurate, reliable, cost-effective predictor of bony involvement except for central arch lesions. The feasibility of outer table rim mandibulectomy alone in patients with floor of mouth tumors needs to be examined carefully.

    Description / Table of Contents: In dieser Arbeit wird die Herstellung von Methylacrylat/N-Phenylmaleimid-Co-polymeren verschiedener Zusammensetzung durch radikalische Polymerisation in Cyclohexanon mit Azoisobutyronitril als Initiator untersucht. Die Molenbrüche für N-Phenylmaleimid der vier Copolymeren MP-1, MP-2, MP-3 und MP-4 sind 0,0664,0,2344, 0,3905 und 0,5445. Die Zusammensetzung der Copolymeren wurde durch Elementaranalyse bestimmt. Weiter wird die änderung der Huggins-Konstante KH mit der Zusammensetzung für die Copolymeren in den Lösungsmitteln Dimethyl-formamid, Methylethylketon und Cyclohexanon beschrieben. KH hängt vom Lösungsmittel und von der Zusammensetzung der Copolymeren ab.
    Notes: This paper deals with the synthesis of methyl acrylate/N-phenylmaleimide copolymers having different compositions, (mole fractions of N-phenylmaleimide for the four copolymers MP-1, MP-2, MP-3, and MP-4 are 0.0664, 0.3905 and 0.5445, respectively) by free radical solution polymerization in cyclohexanone using azoisobutyronitrile as an initiator. The compositions of the copolymers have been determined by elemental analysis. The variation of the Huggins constant KH with composition for the copolymers in three solvents, methyl ethyl ketone, dimethylformamide and cyclohexanone is described. KH is found to be dependent both on solvent and composition of the copolymers.

    Notes: Free-radical copolymerization of methyl acrylate (MA) with N-p-chlorophenylmaleimide (NPCMI) and N-p-bromophenylmaleimide (NPBMI) initiated by AIBN in cyclohexanone solution at 75°C was studied. The copolymer composition has been determined from the nitrogen content and NMR spectra of the copolymers. The reactivity ratios have been calculated by ML, FR, KT, and JJ methods. Q and e values of NPCMI and NPBMI have also been calculated by the Alfrey-Price Q-e scheme.
