The present disclosure pertains to methods and/or systems for making a SIPN and/or an IPN by physically mixing at least one vinyl functional thermoset with at least one thermoplastic resin. For example, a method of producing a resin composition comprising: mixing at least one vinyl functional thermoset resin with at least one thermoplastic resin wherein: the two resins are sufficiently miscible at a mixing viscosity of at least at least 5,000 cPs measured at the temperature of mixing and the mixing results in sufficient laminar flow such that a substantial portion of the resin mixture forms an IPN and/or a SIPN. The IPNs and/or SPINs formed have one or more superior properties over mixtures of the same resins.

[Problem] To provide a gel which can be produced in a short time, has controlled properties such as modulus and expansion pressure, and has a low polymer concentration.

[Solution] A process for producing a polymer gel in which gel-precursor clusters have been crosslinked with one another to form a three-dimensional network structure, characterized by comprising a) a step in which monomer or polymer units that are present in a concentration less than a critical gelation concentration are crosslinked to form the gel-precursor clusters, the gel-precursor clusters having a storage modulus G and a loss modulus G which satisfy the relationship G<G, and b) a step in which the gel-precursor clusters are crosslinked with one another by a crosslinking agent to obtain a gel having a three-dimensional network structure.
