Polypropylene resins of the present invention give blow molded containers excellent in transparency, impact resistance and flexibility. Stretch blow molded containers obtained from the polypropylene resins enable volume reduction and weight reduction. A polypropylene resin includes a random polypropylene (P1) having MFR (ASTM D 1238, 230&#xb0; C., 2.16 kg load) of 0.5 to 100 g/10 min and an ethylene content of 3.0 wt % to less than 7.0 wt %, (i) the resin containing the random polypropylene (P1) at not less than 80 wt %, (ii) the resin showing a broad DSC melting curve which has a single melting point peak and in which the maximum intensity peak temperature (Tm) is not more than 120&#xb0; C. and the half-value width on a higher temperature side from the maximum intensity peak is not less than 20&#xb0; C.

Polypropylene resin and blow molded container

The present invention provides a binder resin solution composition, and a coating, ink, and adhesive containing the composition as an active ingredient, the binder resin solution composition having a solid content of 10 to 50 wt. % and comprising (a) a chlorinated polyolefin prepared by chlorinating to a chlorine content of 10 to 40 wt. % an ethylene-propylene-butene ternary random copolymer having an ethylene content of 3.0 to 3.7 mol %, 1-butene content of 2.4 to 2.8 mol %, and melting point of 129 to 133&#xb0; C., and (b) an organic solvent.

Binder resin solution composition, coatings, inks, adhesives and primers

The present invention provides a binder resin solution composition, and a coating, ink, and adhesive containing the composition as an active ingredient, the binder resin solution composition having a solid content of 10 to 50 wt. % and comprising (a) a chlorinated polyolefin prepared by chlorinating an isotactic polypropylene polymer having a molecular weight distribution of no more than 3 and a melting point measured by a differential scanning calorimeter of 110 to 140&#xb0; C. to a chlorine content of 10 to 40 wt. % and, (b) an organic solvent.
