Crystallization and morphology of binary blends of linear and branched polyethylene,d higher molar mass samples of various linear and branched polyethylenes. Cocrystallization and segregation phenomena occurring in these polymers are reported as a function of molar mass and degree of chain branching of the high molar mass component, blend composition, and crystallization temperatur

Electron microscopic investigation of the crystallization behavior of polymer blends,s of the semicrystalline structure. Electron microscopy was used to reveal the morphology and the crystallization behavior of several polymer blends. In blends of SAN and polyurethane (PU) there is an increased affinity of the PU to SAN, yielding lamellae of PU-like needles in the SAN matrix. A modi

Role of adsorption process during crystallization of polymers at low supercooling,ions prior to crystallization are then changed. Following the De Gennes analysis it is shown that this process leads to segregation effect; chains shorter than .* do not crystallize. The critical mass .* varies with the supercooling . as .*=.., as was found experimentally by Wunderlich.

Polymer nucleating agents: Efficiency scale and impact of physical gelation,stallization temperatures of a non-seeded and of an “ideallly” seeded sample, respectively, gives a measure of the efficiency fo a given nucleating agent which induces the crystallization of the polymer at .. Typical values of . for isotactic polypropylene are given. — The outstanding efficiency of
