چکیده
The dispersion copolymerization of methyl methacrylate (MMA) with macromonomeric azoinitiator, MIM-400, as a macrocrosslinker initiated by the benzoyl peroxide (BPO)/N,N 0dimethylaniline (DMA) coupled in water/ethanol (4/1, v/v) at 208C was carried out to yield PEG-b-PMMA networks with labile azo linkages in the main chain. Gel fraction, swelling ratios (qv) and the average molecular weights between junction points (Mc) values of the networks were investigated. Maximum gel fraction was obtained using 0.133 M MIM-400, 9.2 × 10 M BPO, 2.1 × 10 M DMA and 2.19 M MMA. q 1999 Elsevier Science Ltd. All rights reserved.

Interpolymer complexation is associated with the formation of hydrogen bonds between pendent and/or grafted groups of a single polymer or copolymers. The degree of complexation can be described theoretically in terms of complexation/decomplexation equilibrium characteristics. Graft copolymer networks of poly(methacrylic acid-g-ethylene glycol) were prepared by free radical solution polymerizati...

High-energy mechanical milling has been performed on poly(methyl methacrylate) (PMMA) at ambient and cryogenic temperatures, as well as on polyisoprene (PI) and poly(ethylene-alt-propylene) (PEP) at cryogenic conditions only. Milling conducted at ambient temperature has a substantially greater impact on the molecular characteristics of PMMA than milling at cryogenic temperatures. An increase in...

Six generations of lactodendrimers based on poly(amidoamine) were studied in dilute solutions of 0.2 M NaCl by methods of molecular hydrodynamics (velocity sedimentation and viscometry) and optics (static and dynamic light scattering). Molecular weights, sedimentation and diffusion coef®cients, and intrinsic viscosity values were measured. These data were analysed and compared with previous res...

A model was developed to describe the overall dissolution kinetics of semicrystalline PVA gels prepared by freezing and thawing techniques. The dissolution process was described as a three-step mechanism: detachment-, diffusion-, and disentanglement-controlled dissolution. The unfolding of crystalline regions due to detachment and diffusion was calculated. The lamellar thickness of a PVA crysta...

In this research, hybrid materials based on poly(methyl methacrylate) and silica were synthesized via sol±gel process. Their glass transition behavior was investigated by differential scanning calorimeter. In DSC measurement, 1808C heat-treated hybrid materials exhibited higher miscibility as compared to untreated materials. Relationship between miscibility variation of hybrid materials and hea...
