The bioglass was prepared by hydrolysis and polycondensation of tetraethyl orthosilicate [TEOS], triethyl
phosphate [TEP], calcium nitrate tetrahydrate [[(CaN[O.sub.3]).sub.2] x 4[H.sub.2]O], potassium nitrate [KN[O.sub.3]] and magnesium nitrate hexahydrate [Mg[(N[O.sub.3]).sub.2] x 6[H.sub.2]O] mixed in stoichiometric amounts to obtain the nominal composition of 58Si[O.sub.2], 26CaO, 6[P.sub.2][O.sub.5], 5[K.sub.2]O and 5MgO (mol %).
Azelaic acid (AZA) LR (99%), maleic anhydride LR (98%), triethyl
amine LR (99%), trimethylol propane (TMP, 98%), neopentyl glycol (NPG, 99%), and catalyst AIBN were procured from s.d.
Citrate esters include triethyleitrate, acetylated triethyl
citrate, tributyl citrate, and acetylated tributyl citrate.
In the liver, tetramethyl lead turns into a much more toxic triethyl
lead and causes the increase in the amount of lead in the urine.
This system consists of nickel carboxylate, boron trifluoride diethyl etherate ([BF.sub.3] [Et.sub.2]O), and triethyl
aluminum (TEAL) [6, 7], The BR produced by this system (Ni-BR) has higher linearity and a wider molecular weight distribution with a greater content of ns-1,4 configuration (>97%) than that of BR produced by the Co-based system (ca.
aluminum (TEA, 1 M in hexane) was used as an activator and purchased from Aldrich, Canada.
