    Notes: Poly(oxytrimethylene) (POT) has been found to form inclusion complexes with cyclodextrins to give crystalline compounds in high yields. The yields of the complexes of POT with α-cyclodextrin increased with increase in the molecular weight of POT, reached a maximum at a molecular weight of about 1000, and then decreased with the molecular weight. The stoichiometries are 1:1.5-2 (CD:monomer unit) when the molecular weight of POT is less than 2000. β-Cyclodextrin gave complexes with POT in a 1:2-2.5 ratio when the average molecular weights were less than 2000. When the molecular weight of the polymer was higher than 3000, the ratio of the monomer unit to cyclodextrin increased with increase in the molecular weight. The binding modes are discussed.

    Description / Table of Contents: Die Copolymerisationen von 1,3-Dioxolan mit Tetrahydrofuran, 3,3-Bischlormethyloxetan und 4-Chlormethyl-1,3-Dioxolan wurden mit Borfluoridätherat als Katalysator durchgeführt. Die Copolymerisationsparameter bei 0°C wurden bestimmt. Die Auftragung 1/r1 gegen pKb eines jeden Monomeren ergab eine Gerade, was darauf schließen läßt, daß die Basizität bei der Bestimmung der Copolymerisationsparameter der kationischen Polymerisation wichtig ist.
    Notes: Copolymerization of 1,3-dioxolane with tetrahydrofuran, 3,3-bis(chloromethyl)oxacyclobutane, and 4-chloromethyl-1,3-dioxolane were performed using boron fluoride etherate as catalyst. The monomer reactivity ratios at 0°C. were determined. The plot of log 1/r1 vs. pKb of each monomer gave a straight line, which suggests that basicity of cyclic ethers may be important in determining monomer reactivity ratios in their cationic copolymerization.
