THE EFFECTS OF REACTION VARIABLES ON SOLUTION POLYMERIZATION OF VINYL ACETATE AND MOLECULAR WEIGHT OF POLY(VINYL ALCOHOL) USING TAGUCHI EXPERIMENTAL DESIGN

Poly(vinyl acetate) is synthesized via solution polymerization, and then it is converted to poly(vinyl alcohol) by alkaline alcoholysis.The aim of the work study was to investigate statistically the influence of reaction variables in vinyl acetate polymerization, the conversion of this monomer to polymer, degree of branching of acetyl Thermal Print

In article the question of processing of such types of waste as worn-out Left Side Cover car tires and a concrete crowbar acquiring special relevance in the sphere of the ekologo-focused innovative development is considered.In article the main engineering procedures of a recycling of car tires both from the point of view of ecological safety, and f

In high speed electrical 3 Piece Sectional with Cuddler machines, one of the main challenges that can be faced is the high frequency losses in the machine windings due to both skin and proximity effects.This paper studies the effect of using different types of magnet wires on the AC losses in the winding of high speed electric machines.Using finite

In order to improve the ability of clean energy consumption and the reliability of power supply, distribution network operation is attracting more and more attention.In view of the non-convergence of the Flange Nut traditional forward and backward substitution method, an improved power flow algorithm for distribution network with ring network was p

Abstract Pineapple originates from tropical regions in South America and is therefore significantly impacted by cold stress.Periodic cold Food Jar events in the equatorial regions where pineapple is grown may induce early flowering, also known as precocious flowering, resulting in monetary losses due to small fruit size and the need to make multipl
