An experimental of kinetics investigation of the solution free radical polymerization of isopropylacrylamide (IPAM) initiated with potassium persulfate (PPS) was conducted. The reactions were carried out at constant temperature of 60 °C in distilled water under unstirred and inert conditions. Using the well-known conversion vs. time technique, the effects of initiator and monomer concentration on the rate of polymerization (Rp) were investigated over a wide range. Under the conditions of our work, the orders 0.38 and 1.68 were found with respect to initiator and monomer, respectively. However, the rate of polymerization (Rp) is not straight forwardly corresponding monomer concentration. The value 46.11 kJ mol1 was determined as the o

Al-sarf science is one of the most scientifically accurate and rich in branches. Because it depends on the one accent and how the changes happened inside this science (from an event associated with time or not associated). The people who create this science and were deep made a tough rule to can out of these sentences without reason. The aim of this research is to declare (The Impossible Phenomenon in the Preference Name) and this study is separated into two chapters: 

Section one: it’s content of (Preference) in the base books and the scientists of linguists and the rules that authorized building in the name of Preference.
