A computer automated thermal analysis laboratory for polymer characterization
TLDR
A software package is described that has been developed for use with a DEC PDP 11/40 computer system, which eliminates nearly all of the hand calculations and plotting that are normally encountered for DSC, TG, TMA and evolved gas techniques (TEA, TGC).About:

Thermal analysis of water in p(HEMA) hydrogels
TL;DR: Hydrogels composed of poly(hydroxyethyl methacrylate) (pHEMA) and water were investigated using differential thermal analysis and adiabatic calorimetry and show that the crystallization of water in the gels is a very gradual process, leading to the development of a metastable, non-equilibrium state.

Polyether Based Thermoplastic Polyurethanes Effect of the Soft Segment Molecular Weight
TL;DR: A series of polyether-based thermoplastic polyure thanes, varying in soft segment molecular weight and hard seg ment content was prepared and studied in this paper, where they were used to construct poly(oxypropylene- oxyethylene) diols.
Journal ArticleDOI
Modern Methods of Thermal Analysis
TL;DR: The position and importance of thermal analysis among methods of material research and structure elucidation is well shown by the review which appeared in Research and Development Journal as mentioned in this paper, which showed that about 42% of the laboratories surveyed are using, or expect to be using in the near future, thermogravimetric (TG), differential thermal analysis (DTA), or differential scanning calorimetric devices.

RIM Urethanes Structure/Property Relationships for Linear Polymers
TL;DR: Reaction injection molding (RIM) technology represented the major break-through in the polymer processing development of the seventies as discussed by the authors, based on the rapid mixing of co-reactive streams and subsequent feeding of the mixture into the polymerization reactor, allowing for production of large and intricate parts.

Pyrolysis-molecular weight chromatography: A new on-line system for analysis of polymers. II. Thermal decomposition of polyolefins: Polyethylene, polypropylene, polyisobutylene
Erdogan Kiran,John K. Gillham +1 more
TL;DR: In this paper, the thermal decomposition of low-density polyethylene, isotactic polypropylene, and polyisobutylene has been studied in helium at a heating rate of 20°C/min using an experimental system which consists of a programmable pyrolyzer, a thermal conductivity cell, and a mass chromatograph.

The states of water in cellulose acetate membranes
TL;DR: Differential scanning calorimetric melting endotherms of wet and half-dried cellulose acetate membranes and salt distribution coefficients were studied to clarify the states of water in membranes.
Journal ArticleDOI
The application of digital and analog computers to thermal analysis
TL;DR: The applications of digital and analog computers to problems in thermal analysis are reviewed in this article, where all of the applications are of a passive type in which there is no significant computer control of the experiment.

Evaluation of kinetic parameters from TVA data. A computer simulation approach
TL;DR: A simple computer simulation of linear temperature-programmed thermal volatilization analysis (TVA) provides useful insights into the effects of the order of reaction n, the Arrhenius preexponential factor A, the overall activation energy δE, and the linear rate of heating β on the position and shape of TVA thermograms.
