| Abstract: | LDPE/PP co PE blends are prepared by solution blending and freeze drying, and characterized by DSC and selective extraction. The dependence of compatibility of the blend system on composition and quench conditions is discussed. Freeze drying is demonstrated to be a useful method to promote the compatibility of the blend system. |
