Off-lattice simulation of multifunctional monomer polymerizations: effects of monomer mobility, structure, and functionality on structural evolution at low conversion:

Article Abstract:

An off-lattice kinetic gelation model with refinements to the representations of monomer mobility, structure, and functionality, which more realistically capture low conversion propagation events during cross-linked network evolution, is reintroduced. The utility of a unique approach for kinetic gelation simulation of multifunctional monomer polymerizations that afford more realistic representation of monomer structure and dynamics than traditional, lattice-based models is demonstrated.

Relationship between packing structure and monomer reactivity in the photo induced solid-state polymerizations of muconic diesters with different side groups

Article Abstract:

A study is conducted to clarify the relation between packing structures and reactivity of monomer molecules in the photoinduced slid-state polymerization by analyzing crystal structure. The systematic study of the molecular packing geometry for a series of muconate derivatives brought up a very important warning about the conventionally made discussion on the factors governing the solid-state polymerization reaction based on the interatomivc distance.

Effect of cross-link density on the internal structure of poly(N-isopropylacrylamide) microgels

Article Abstract:

The static and dynamic light scattering measurements are used to investigate the effect of cross-link density on the structure of poly(N-isopropylacrylamide) microgel particles prepared by emulsion polymerization. The measurements show that the gel particles cannot be considered as homogeneous spheres.
