Semicrystalline thermoplastic polymers, characteristic

Semicrystalline PP is a thermoplastic material containing both crystalline and amorphous phases. The relative amount of each phase depends on structural and stereochemical characteristics of the polymer chains and the conditions under... 

The blending of semicrystalline biodegradable and fiiendly environmental thermoplastic such as bacterial poly(3-hydroxybutyrate) (PHB) with one of the cheapest packing or industrial polymer such as low-density polyethylene (LDPE) and with hydrophilic polyvinyMcohole (PVA) is a perspective tool to obtain novel materials with combined characteristics of the origin components along with economic advantages for material performance. 

Although this definition still fits most materials called IPNs, now some hybrid polymer blends, such as thermoplastie ayyarent IPNs, call for a broader concept [3,7,8]. In contrast to the chemically crosslinked IPNs, physical bonds are characteristic of the crosslinking in thermoplastic apparent IPNs. These physical bonds are glassy domains of block copolymers, ionic clusters in iono-mers, or crystalline domains in semicrystalline polymers. The components of thermoplastic IPNs are capable to form physical networks and are characterized by interpenetration of phases. Thermoplastic apparent IPNs take an inter-...
