Preparation of dual-cross network polymers by the knitting method and evaluation of their mechanical properties

Abstract Bulk copolymerization of alkyl acrylates and cyclodextrin (CD) host monomers produced a single movable cross-network (SC). The CD units acted as crosslinking points in the obtained SC elastomer. Introducing crosslinks into poly(ethyl acrylate/butyl acrylate) copolymer resulted good toughness ( G f ) stress dispersion. Here, to improve Young’s modulus E elastomers, bulk liquid acrylate monomer swelling gave another type elastomer with penetrating polymers (SCPs). Moreover, presence dual (DC) elastomers. DC suitable weight % (wt%) secondary polymer was higher than those SCP or combination hydrophobicity glass transition network important for improving . Small-angle X-ray scattering (SAXS) indicated that elastomers exhibited heterogeneity at nanoscale. showed significantly broader relaxation time distribution Thus, nanoscale were increase This method fabricate would be applicable conventional polymeric materials.
