Abstract
|
|
|
|
Polydimethylsiloxane(PDMS)-co-poly(2-hydroxyethyl methacrylate)(PHEMA) was prepared and the degree of swelling of solvents into the polymers was examined. It was confirmed that the solubility parameter of PHEMA homopolymer is 26 (J/cm3)1/2. Ethanol was significantly absorbed into copolymers containing large amount of PHEMA, while tetrahydrofuran was effectively absorbed into copolymers containing large amount of PDMS. Absorption of polar solvents into the copolymers were increased with the increase of PDMS content. The model drug, crystal violet (CV), was more absorbable into PDMS-HPEMA copolymers than PHEMA homopolymer. Absorption of CV was decreased with the increase of PDMS content of the copolymers.
