Jl. Nunez et al., Interaction of poly methyl vinyl ether/maleic anhydride-dimiristoyl phosphatidylcholine: a model bioadhesion study, BIOMATERIAL, 21(21), 2000, pp. 2131-2135
The objective of this work is to study the interaction of a copolymer, poly
methyl vinyl ether/maleic anhydride (PMV/MA) used in pharmaceutical dosage
form and a phospholipid L-alpha-dimiristoyl phosphatidylcholine (DMPC) wit
h the aim of developing a bioadhesive system. Glycerine is the plastifiant
used to make PMV/MA insoluble. We have studied copolymer-plastifiant compat
ibility with differential scanning calorimetry and we have studied the infl
uence that the solvents produce on the copolymer by infrared spectroscopy.
Monolayer experiments were carried out with a Wilhelmy-type surface balance
. The purpose of these experiments is to obtain molecular information about
interaction PMV/MA-glycerine system with DMPC. The results show that there
are attractive forces and it is a spontaneous process. (C) 2000 Published
