چکیده

The MW profiles of proanthocyanidin polymers (condensed tannins) from 32 samples representing a wide range of plant tissues of many different species have been obtained by gel permeation chromatography of the peracetate derivatives. The tannins vary widely in MW, with Al. values for the peracetates in the range 1600-5500. The MW profiles vary greatly from those with narrow, rather smooth distributions, to those which are discontinuous.

مطالعه اثر ریزساختار پلی‌بوتادین خاتمه‌یافته با هیدروکسیل (HTPB) بر خواص مکانیکی کامپوزیت پرانرژی

The mechanical properties of the final energetic composite depend mainly on the HTPB prepolymer microstructure; thus, the prepolymer microstructure of HTPB is one of the important factors influencing the mechanical properties of high-energy composite based on HTPB resin. In this paper, the effect of microstructure parameters of HTPB on the behavior and mechanical properties of its high-energy c...

Synthesis and Characterization of Biodegradable Low Molecular Weight Aliphatic Polyesters and Their Use in Protein-Delivery Systems

Poly(lactic acid) (PLA) and poly(lactic-coGA) (PLGA) with low molecular weights were synthesized by a one-step polycondensation of lactic acid (LA) with glycolic acid (GA) molecules using stannous octoate as a catalyst at 160°C. A high yield ( 80%) of all the polymers was obtained in the study. The PLA and PLGA copolymers were characterized by H-NMR, GPC, and DSC measurements, etc. We elaborate...

Interfacial glass transition profiles in ultrathin, spin cast polymer films.

Interfacial glass transition temperature (T(g)) profiles in spin cast, ultrathin films of polystyrene and derivatives were investigated using shear-modulated scanning force microscopy. The transitions were measured as a function of film thickness (delta), molecular weight, and crosslinking density. The T(g)(delta) profiles were nonmonotonic and exhibited two regimes: (a) a sublayer extending ab...

Lipid substitution on low molecular weight (0.6-2.0 kDa) polyethylenimine leads to a higher zeta potential of plasmid DNA and enhances transgene expression.

Cationic polymers are desirable gene carriers because of their better safety profiles than viral delivery systems. Low molecular weight (MW) polymers are particularly attractive, since they display little cytotoxicity, but they are also ineffective for gene delivery. To create effective carriers from low MW polymers palmitic acid (PA) was substituted on 0.6-2.0 kDa polyethylenimines (PEIs) and ...
