The main goal of the current study was to investigate the influence of adding chitosan grafted onto acrylic acid as a superabsorbent base material on the properties and characteristics of the resulting superabsorbents. The method used to prepare the superabsorbent was the gamma...
We also suggest, in regard to temperature characteristics of ionic conductivity and reciprocal dielectric relaxation time, that the driff of ions is related to the motion of acrylic elastomer chains. The carrier mobility in the acrylic elastomer-LiCIO4 complex was measured by using the voltage ...
These naturally occurring unsaturated fatty acids have certain characteristics. (1) If there are two or more carbon-carbon double bonds, each double bond is separated from the next by a CH2 (called methylene) group. (2) Virtually all double bonds in these and other naturally occurring unsaturate...
Explore key features, uses, main applications, advantages & disadvantages for Acrylonitrile Butadiene Styrene (ABS Plastic) an opaque engineering thermoplastic.
Improved eco-friendly characteristics could include the use of a biobased polymer and the development of a recycling protocol. High cellulose content, and favorable wood-polymer stress-transfer are important reasons for the reinforcement effects; and PMMA is well-distributed also at nanoscale due to ...
The use of fillers is one of several methods widely used to improve the properties of polymeric materials. Both basic scientific information and useful engineering data can be obtained from the introduction of inorganic fillers. It should be noted that the study of filled polymer blends have been...
Poly(ε-caprolactone) has a melting point of 59-64°C and a glass transition temperature of -60°C. It is a low molecular weight, colorless crystalline solid with a waxy texture. The introduction of ester groups -coo- in the molecular structure makes it easily biodegradable by microorganisms ...
The obtained data indicate that crosslinking generally improves the PSA properties related to their use in flexible display applications; however, very high crosslinking densities produce mostly a negative effect on the PSA flexibility and adhesion characteristics 展开 关键词: Acrylic pressure sensitive ...
The effects of blend ratio and vulcanizing systems on the cure characteristics and mechanical properties, such as stress–strain behaviour, Young's modulus, tensile strength, elongation at break and hardness of SBR/NBR blends, were studied. Blends prepared by using sulfur as the vulcanizing agent ...
