Two poly(Schiff base)s (PDBT and PDPE) were synthesized by polycondensation of 1,10-phenanthroline-5,6- dione (PD) with 2,2′-diamino-4,4′-bithiazole (DABT) an
<正>The brittle-ductile transition is a very important phenomenon for polymer toughening. Polypropylene (PP) is often toughened by using rubbers, e.g., ethylene
<正>Monodisperse hollow polymer microspheres having various functional groups on the shell-layer,such as carboxylic acid,pyridyl and amide,were prepared by two-
