Melt network

Ewen, B, Richter, Da Neutron Spin Echo Investigations on the Segmental Dynamics of Polymers in Melts, Networks and Solutions. VoL 134, pp, 1-130. 

This paper reviews NSE measurements on polymer melts, networks and solutions, published since the first successful NSE study on polymers [16] was performed in 1978. The experimental observations are discussed in the framework of related microscopic models, scaling predictions or other theoretical approaches. 

This article gives a comprehensive review of NSE investigations performed on the large-scale motion of polymers of various architectures in melts, networks... 

With respect to their physical properties, boron is a black, hard, very high-melting, network covalent metalloid, but the other 3 A members are shiny, relatively soft, low-melting metals. Aluminum s low density and three valence electrons make it an exceptional conductor for a given mass, it conducts a current twice as effectively as copper. Gallium has the largest liquid temperature range of any element it melts in your hand but does not boil until 2403°C. 

Z doesn t condnct, is chemically inert, and is high melting (network solid). Of the choices, it must be quartz (Si02). 

The monomer must be non-aromatic, otherwise crosslinking will not occur. The polyester and reactive diluent crosslink with heat and/or free radical initiation into a soKd non-melting network.
