Polymer network, interpenetrating sequential

This is a theoretical study on the structure and modulus of a composite polymeric network formed by two intermeshing co-continuous networks of different chemistry, which interact on a molecular level. The rigidity of this elastomer is assumed to increase with the number density of chemical crosslinks and trapped entanglements in the system. The latter quantity is estimated from the relative concentration of the individual components and their ability to entangle in the unmixed state. The equilibrium elasticity modulus is then calculated for both the cases of a simultaneous and sequential interpenetrating polymer network. [Pg.59]

These soft elastomers can be swelled by other monomers such as styrene, which together with crosslinkers such as divinylbenzene, can be polymerized in situ to form a sequential interpenetrating polymer network, IPN. Alternately, and in some cases preferably, the two polymerizations can be carried out simultaneously, since the esterification of the oil and the vinyl polymerization do not significantly interfere with one another. These latter products are called simultaneous interpenetrating networks, SINs. [Pg.96]

The effect of silicone oil and carboxylated silicone on intraocular lenses was studied with FTIR spectroscopy. It was noticed that washing with n-pentane removed the adhered silicone oils from two types of lenses, while residual oil was detected in other cases [22], The development of sequential interpenetrating polymer network (IPN) based on poly(2-methacryloyloxyethylphosphorylcholine) and silicone was studied with FTIR spectroscopy. It was discovered that IPN possesses reduced protein absorption tendency compared to pristine silicones and can be used as a novel ophthalmic biomaterial [23]. The stimuli responsive ultra-thin diblock copolymer brushes were developed on the surface of silicone rubber and studied with FTIR spectroscopy. The authors studied the thermally-induced evolution mechanism of various interactions using... [Pg.181]
