Analogy between Polymer Blends and Crystalline Homopolymers

ANALOGY BETWEEN POLYMER BLENDS AND CRYSTALLINE HOMOPOLYMERS 

In the earlier discussion of the properties of crystalline homopolymers in the bulk state (Chapter 1), it was shown that such polymers always contain some amorphous material, various segments of the same chain lying in crystalline or amorphous regimes (Krigbaum et al, 1964). If the amorphous portion is above its 7, i.e., is elastomeric, a direct analogy exists between such materials and polymer blends, blocks, and grafts, in which the formation of hard and soft domains is induced by the use of polymer components differing in chemical composition and inherent properties thus, as pointed
