    Molecular-weight dependence of the glass transition temperatures of rigid SIS triblock copolymers studied by DSC (1982)

    Description / Table of Contents: Zusammenfassung DSC wurden an einer Reihe von ABA Poly(styrol-b-isopren) Dreiblock-Kopolymeren mit 30% Polyisoprengehalt und verschiedenen Molekulargewichten durchgeführt. Die DSC-Daten zeigen eine innere Verschiebung der Glas-Übergangstemperaturen (T g) der Blöcke im Vergleich zu den entsprechenden Homopolymeren. Als Funktion des Molekulargewichts wurden ein bis drei Übergänge gefunden. Die zusätzliche dritteT gerbringt weitere Beweise bezüglich der Existenz einer Interphase zwischen den Mikrodomänen.
    Abstract: Резюме Проведены ДСК-измере ния ряда АБА поли(стирол-Ь-изопрен) трехблочных сополимеров с различ ным молекулярным вес ом и содержащих 30% полиизоп рена. Данные ДСК показали внутрен ний сдвиг температур ы стеклообразования (T g) блочных сополимеров по сравнению с соотве тствующими гомополи мерами. В зависимости от молек улярного веса полимеров было н айдено от одного до тр ех переходов. Наличие до полнительного третьегоТ g перехода служит дальнейшим доказательством сущ ествования какого-ли бо межфазного состояни я между микродоменам и.
    Notes: Abstract Differential scanning calorimetry (DSC) measurements have been carried out on a series of ABA poly(styrene-b-isoprene) triblock copolymers with 30% polyisoprene content and various molecular weights. The DSC data show an inward shift for the glass transition temperatures (T g) of the blocks compared to the corresponding homopolymers. As a function of the molecular weight, one to three transitions were found. The additional thirdT g gives some further evidence of the existence of an interphase between the microdomains.

    Adhesion of block copolymers to glass: Lap shear strengths as a function of bonding conditions (1983)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: ABA poly(styrene-b-isoprene) block copolymers with various molecular weights and composition were used as heat activated films in simple overlap glass joints. The influence of bonding temperature on their shear strength at break was investigated. On increase of temperature, the joint resistance for most of the copolymers passed through a maximum, which temperature was dependent on the molecular characteristics of the copolymers. The decrease in melt viscosity or chemical degradation could not explain the data. A morphological interpretation which fits well the present and previous observations is proposed and verified for one copolymer used in this work.

    Effect of crosslink density and internetwork grafting on the transparency of polyurethane/polystyrene interpenetrating polymer networks (1988)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 36 (1988), S. 1467-1473 
    Details
    ISSN: 0021-8995
    Keywords: Chemistry ; Polymer and Materials Science

    Notes: Because of their incompatibility and the different refractive indices of the homopolymer components, polyurethane/polystyrene interpenetrating polymer networks are turbid by nature. Different parameters likely to enhance their transparency are examined: the crosslink density of each network and the level of internetwork grafting. The results prove that the latter factor is the most effective, as in some cases, very clear and transparent samples are obtained. Correspondingly, preliminary investigations of the dynamic mechanical properties show an inward shift of the glass transition temperatures for such systems. It is concluded that parameters able to cause a higher degree of phase dispersion can yield transparent materials.

    Compatibility of ABA poly(styrene-b-isoprene)/poly(2,6-dimethylphenylene oxide) blends (1978)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: A variety of blends of ABA poly(styrene-b-isoprene) copolymers with poly(2,6-dimethylphenylene oxide) were prepared. Their compatibility was examined by measuring both the apparent modulus of rigidity and the loss tangent. Several blends showed a unique glass transition temperature between those of the individual components, which indicated compatibility. It was found that only those copolymers which phase separate are compatible with poly(2,6-dimethylphenylene oxide).

    Glass transition temperatures of ABA poly(styrene-b-isoprene) block copolymers by differential scanning calorimetry (1982)
    New York : Wiley-Blackwell
    Journal of Polymer Science: Polymer Physics Edition 20 (1982), S. 389-398 
    Details
    ISSN: 0098-1273

    Topics: Chemistry and Pharmacology , Physics
    Notes: The glass transition behavior of two sets of ABA poly(styrene-b-isoprene) block copolymers was examined by differential scanning calorimetry. In one series, the triblock copolymers had different total molecular weights and the same (30 wt %) polyisoprene content, in the other, the molecular weight was constant (30,000 g/mol) and the elastomer content was the variable. For all triblock copolymers studied, the data show an inward shift for the glass transition temperatures Tg of the corresponding homopolymers. This shift increases for the rigid-phase Tg as the polystyrene block length decreases. Depending on their molecular characteristics, two, three, or only one Tg were found. The third Tg was interpreted in terms of the existence of an interphase. Some of these conclusions could be confirmed by transmission electron microscopy.
