126. Increased spherulitic growth rates of semicrystalline polymer due to enhanced limited local chain segmental mobility at the interface of double-layer thin films
Abstract： In this work the nucleation and growth of spherulites for the below polylactide (PLA) layer in poly(ε-caprolactone)/polylactide (PCL/PLA) double-layer films during isothermal crystallization at various temperatures above the melting point of PCL have been investigated by using polarized optical microscopy (POM). It is revealed that two types of spherulitic morphologies ...

[J. Am. Chem. Soc.] Rare Earth Metal-Mediated Group-Transfer Polymerization: From Defined Polymer Microstructures to High-Precision Nano-Scaled Objects
Poly(2-isopropenyl-2-oxazoline) (PIPOx) and poly(2-vinylpyridine) (P2VP) have been efficiently synthesized using bis(cyclopentadienyl)methylytterbium (Cp2YbMe) as catalyst. The polymerizations of 2-isopropenyl-2-oxazoline (IPOx) and 2-vinylpyridine (2VP) follow a living group-transfer polymerization (GTP) mechanism, allowing a precise molecular-weight control of both polymers with very narrow mo...

Cure Kinetics of an Epoxy Resin Containing Naphthyl/Dicyclopentadiene Moieties and Bis-Phenoxy (3-Hydroxy) Phosphine Oxide System and Properties of Its Cured Polymer
The cure kinetics of naphthyl/dicyclopentadiene epoxy resin and bisphenoxy (3-hydroxy) phosphine oxide was investigated by differential scanning calorimetry (DSC) under nonisothermal and isothermal condition. The advanced isoconversional method was used to study the nonisothermal DSC data, the effective activation energy of the curing system in the early stage agreed with the value Calculated from...

Polymer 2011:Fabrication and stability of porous poly(allylamine) hydrochloride (PAH)/poly(acrylic acid) (PAA) multilayered films via a cleavable-polycation template
Porous films were fabricated from nonporous layer-by-layer multilayers composed of a blend of positively charged disulfide-containing polyamidoamine and poly(allylamine hydrochoride), and negatively charged poly(acrylic acid), followed by removal of cleavable disulfide-containing polycation after incubation in 1 mM DTT solution. The thickness of original multilayered films decreased with the incre...

[Biomacromolecules] Photoactivation of Alkyl C-H and Silanization: A Simple and General Route to Prepare High-Density Primary Amines on Inert Polymer Surfaces for Protein Immobilization
Surface modification through implanting functional groups has been demonstrated to be extremely important to biomedical applications. The usage of organic polymer phase is often required to achieve satisfactory results. However, organic surfaces usually have poor chemical reactivity toward other reactants and target biomolecules because these surfaces usually only consist of simple alkyl (C-H) a...

Unusual rheological behavior of liquid polybutadiene rubber/clay nanocomposite gels: The role of polymer-clay interaction, clay exfoliation, and clay orientation and disorientation
The rheological properties of liquid polybutadiene rubber/organo-clay nanocomposite gels were investigated by rheological experiments, focusing on the effects of clay exfoliation and orientation-disorientation, as well as polymer-clay interaction and temperature. Both irreversible and reversible viscosity transitions were observed in the temperature range from 26 to 136 ?C in st...
