Exploitation of dinuclear salan aluminum complexes for versatile copolymerization of ε-caprolactone and L-lactide.
By combining the influence of excess alcohol, temperature and monomer-to-initiator ratios in the feed, dinuclear salan aluminum complexes L(R)Al(2)Me(4) exhibited a high degree of control towards the copolymerization of L-LA and ε-CL, producing blocky, gradient, tapered and random copolymers.
متن کاملTitanium pyridonates for the homo- and copolymerization of rac-lactide and ε-caprolactone.
A series of titanium pyridonate complexes have been synthesized under very mild reaction conditions from a common precursor, Ti(NMe2)4. These complexes have been explored as initiators for the ring-opening polymerization of rac-lactide and ε-caprolactone and have proven to be competitive with leading titanium initiators. Furthermore, these complexes have been shown to be competent initiators fo...
متن کاملIn vitro release of cytotoxic nucleoside analogs from lactide-caprolactone and lactide-glycolide copolymers.
The aims of our study were to assess the release of cytotoxic nucleoside analogs 5-fluorouracil and 2-chloro-2'-deoxyadenosine from different lactide-glycolide or lactide-caprolactone biodegradable copolymers and the effects of sterilization on this release. The polymers were sterilized either with ethylene oxide at 37 degrees C, or with gamma radiation (15 kGy, 20 kGy, or 25 kGy). The kinetics...
متن کاملKinetics of a nucleoside release from lactide-caprolactone and lactide-glycolide polymers in vitro.
We assessed the rate of release of a model nucleoside (adenosine, 5%, w/w) from nine different lactide-glycolide or lactide-caprolactone polymers. The polymer discs were eluted every second day with an artificial cerebrospinal fluid at the elution rate roughly approximating the brain extracellular fluid formation rate. Adenosine in eluate samples was assayed by HPLC. Three polymers exhibited a ...
متن کاملEthyl 2-hydroxy-2-methylpropanoate derivatives of magnesium and zinc. The effect of chelation on the homo- and copolymerization of lactide and ε-caprolactone.
The preparation, single crystal and molecular structures of the compounds (BDI)Mg(OCMe2COOEt)(L) are described where BDI = 2-[(2,6-diisopropylphenyl)amino]-4-[(2,6-diisopropylphenyl)imino]pent-2-ene and L = pyridine (py) and 4-dimethylaminopyridine (DMAP). In the solid-state the molecules have five coordinate Mg(2+) ions that may be considered as derived from a trigonal bipyramid where the chel...
