Acronal-polymethyl acrylate interpenetrating polymer networks

Four interpenetrating polymer networks were prepared by swelling crosslinked Acronal (a copolymer of styrene and butyl acrylate) with methyl acrylate plus crosslinking agent and then polymerizing the methyl acrylate in situ. Certain properties of the constituent network materials, plus the interpenetrating polymer networks which contained 70, 50, 35 and 25% by weight of polymethyl acrylate, were investigated. Electron microscopy showed the interpenetrating polymer networks to be two-phase materials with the polymethyl acrylate domain size increasing with increasing polymethyl acrylate content. Longitudinal sonic velocity measurements indicate that at around 50% by weight of polymethyl acrylate both phases become continuous while dynamic mechanical spectroscopy leads to the view that the constituent networks were not extensively mixed.

Semi- and fully interpenetrating polymer networks based on polyurethane-polyacrylate systems. IX. Properties of an isomerically related interpenetrating network

Two polyurethane–poly(vinyl acetate) interpenetrating polymer networks of differing composition were synthesized and certain physical properties investigated. The results are compared with semi-1-interpenetrating polymer networks of the same system as well as with, where appropriate, polyurethane-poly(methyl acrylate) interpenetrating polymer networks. Dynamic mechanical analysis clearly indicated phase separation for both compositions. The poly(vinyl acetate) glass transition showed a shift to lower temperatures accompanied by a shift to higher temperatures of the polyurethane transition. Such shifts indicate a certain extent of mixing. Electron microscopy confirmed phase separation and for a material with 20% by weight of polyurethane indicated that both components are continuous. This latter material also had a higher tensile strength and elongation at break than the corresponding poly(vinyl acetate) homopolymer. At 60% by weight of polyurethane the stress-strain characteristics are those of a reinforced rubber. Certain modulus–composition theories, and, also, sonic velocity measurements were consistent with these morphological conclusions.     

Semi- and fully interpenetrating polymer networks based on polyurethane–polyacrylate systems. XI. The influence of polymerization temperature on morphology and properties

Polyurethane–poly(methyl acrylate) interpenetrating polymer networks (IPNs) of fixed composition (50/50) were prepared at 200 MPa and a range of temperatures. Decreased synthesis temperatures generally resulted in improved mixing of the two networks, although the sequence of formation of the two polymers was also important. No obvious improvements in physical properties resulted from the enhanced mixing. At high synthesis temperatures, the exothermic heat of polymerization of the methyl acrylate led to excessive temperatures, capable of degrading the already-formed polyurethane network. This resulted in a deterioration in tensile strength and a decrease in hardness of the IPN. © 1992 John Wiley & Sons, Inc.     

Ionomer interpenetrating polymer networks from polyurethane anionomers and polyurethane isocyanurate

Two-component interpenetrating polymer network (IPN) systems composed from polyurethane isocyanurate and polyurethane anionomer were prepared by simultaneous polymerization and crosslinking in solution. Specific attractive forces that occurred among various networks helped to make them compatible and led to the formation of true homogeneous topologically interpenetrating polymer networks. These ionomer IPNs were characterized by means of stress-strain properties, hardness, thermogravimetric analysis, density and conductivity. The morphology of the IPNs was studied by thermomechanical analysis and dynamic mechanical analysis.
