Study the result enunciation,be to lead into the porogenic agent in the system with the result that the bore,after melting agent extract absorb the oil resin to have the better oil article absorption rate,further certificate absorb the oil rate to the internal bore of resin the dependence of the structure.

The results showed that oil-absorption resin had better oil absorption rate after melting agent extraction when adding melting porogenic agent,which approved the dependent of oil-absorption resin to pole structure of resin.

Due to general oil-absorption resins didn\'t display satisfactory absorption of long carbon-chain oil, inert porogenic agent was introduced into suspension polymerization system, which was expected to enlarge pore structure inside resin and enhance hydrophobic force of resin respectively.

The internal structure of the resin beads can be controlled by parameters in the polymerization recipe such as mole fraction of cross-linker as well as the type and volume of diluent/ porogen/ pore generating solvent, an inert organic solvent,.

For the purpose of three-dimensional scaffolds fabrication with completely interconnected spherical pores for tissue engineering application, a novel water dissoluble spherical porogen was studied in this paper.

Gelatin or NaCl particles were employed as porogen to fabricate biodegradable poly(L-lactide) (PLLA) scaffolds by a porogen-leaching technique.

The influences of coating condition and the content of pore-forming agent on the porous structure and the vapor permeation were studied.

OBJECTIVE To compare the influence of different pore-forming agents and their amount on the release of budesonide enteric-coated sustained-release pellets.

Gels with rapid response rate can be synthesized by using pore-forming agent.

Compared with conventional preparation,adding porogenic agents at the course of synthesis can enhance the adsorption ability of resin toward protein,while the mechanical strength is rather low.
