  • Polymer Blends Containing Liquid Crystals: Review

    plasticizers for thermoplastic polymers and in applications such as electro-optics, optical recording media, and membranes. High molar mass liquid crystalline polymers have been primarily used in polymer blends as processing aids and as an incipient reinforcing phase .

  • Semi-Crystalline Polymers - RTP Company

    Semi-Crystalline Polymers. These materials are anistropic in flow, shrinking less in the direction of flow vs. transverse to flow. They have excellent chemical resistance. Semi-crystallines exhibit substantial improvement in their HDTs when reinforced and retain useful levels of strength and stiffness well beyond their glass transition temperature (Tg).

    Semicrystalline polymers constitute the largest group of commercially useful polymers. These polymers exists as viscous liquids at temperatures above the melting point of the crystals. Upon cooling, crystals nucleate and grow to fill the available volume.

  • Crystalline vs. Amorphous Polymers - Mallard Creek Polymers

    Jul 14, 2017 · Crystalline and Amorphous Polymers. Crystalline structures are generally very ordered, which is what gives them strength and rigidity. Think of diamond or steel as examples. A crystalline polymer, where the molecular chains are largely locked in place against one another, is similar. Apply a load and it will break rather than bend.

  • Difference Between Amorphous and Crystalline Polymers ...

    May 26, 2017 · Crystalline polymers have an ordered structure which is made out of syndiotactic and isotactic polymer chains. This ordered structure cause the polymer to become translucent. There are also strong attraction forces between molecules. Hence, it is chemical resistant and has a high density compared to amorphous polymers.

  • Characterization of a Paint-PMMA Polymer Blend

    polymer blend. An immiscible polymer blend is a combination of two or more polymers that are physically, rather than chemically, mixed together and remain as distinct phases.6 Therefore, the two polymers form a mechanical bond between one another. This contrasts with miscible polymer blends, in which two polymers are mixed together to form a

  • Morphology and Crystallization of Crystalline/Amorphous ...

    Blending is an important method for developing new materials in polymer science, which may combine the properties from the individual components (Paul and Bucknall 2000; Utracki 2002; Nwabunma and Kyu 2007).Crystalline and amorphous polymers are two main categories in polymer family.

  • Crystallization Kinetics and Morphology in Miscible Blends ...

    Oct 01, 1998 · Spherulitic morphology and the melting behavior of the blends were strongly dependent upon the crystallization kinetics and some unique phenomena were .
