The Influence of Polystyrene Modifier and Plasticizer Nature on the Properties of Poly(vinyl chloride)

“…During PVC plasticization by plasticizers of different nature, in particular diesters of phthaleic acid, the phenomena connected with components compatibility play the key role [3][4][5]. The introduction of polystyrene modifier preliminary dissolved in the plasticizer increases PVC wetting by the plasticizer and improves the components compatibility ( Fig.…”

“…Diesters of phthalic acid are widely used as plasticizers for the production of elastic materials based on PVC [2,4]. They have high affinity with PVC, considerable plasticizing ability and high boiling temperature.…”

Russian Military Reform From Perestroika to Putin: Implications for U.S. Policy

“…39 Ibid, 277-280. 40 Ibid, 286-294 and 301-303. 41 Russian military reform during the Yel'tsin years was defined by three major themes: the continuous lack of funds; the massive withdrawals and continuous force reductions that started under Gorbachev but continued through the 1990s, and lack of strong and visionary leadership, either civilian or military.…”

“…As a result, their heavy military equipment was somewhat reduced. 40 Establishing three categories of forces: a) "Permanent Readiness" units, which were to be fully equipped and no less than 80 percent manned, b) "Reduced Strength" units, also fully equipped, but with only 10-50 percent of their compliment during peacetime and thus requiring 30 days to reach readiness, and c) "Strategic Reserve" units, which were primarily unit equipment sets with some maintenance staff. Plans were made for three Permanent Readiness divisions and four brigades in the Moscow, Leningrad and North Caucasus MDs and 21 Reduced Strength Divisions and 10 brigades.…”
