This document discloses a process for manufacturing recyclable injection molded microcellular foams for use in, footwear components, seating components, protective gear components, and watersport accessories. The process includes the steps of providing a thermoplastic polymer which comprises at least one monomer derived from depolymerized post-consumer plastic, inserting a fluid into a barrel of a molding apparatus. The fluid is introduced under temperature and pressure conditions to produce a super critical fluid. The process further includes mixing the thermoplastic polymer and super critical fluid so as to create a single phase solution, and injecting the single phase solution into a mold of an injection molding machine under gas counter pressure. The process further includes foaming the single phase solution by controlling the head and temperature conditions within the mold.

Disclosed herein is a silicone-modified polyimide resin composition of solvent free type. The composition is suitable for use as an adhesive and a coating material which are capable of hardening upon irradiation with ultraviolet rays and/or visible rays. Also, it is saved from drooling even in the case of light filling with an inorganic compound and it is saved from bubble entrapment and nonuniformity at the time of application with heavy filling. It further exhibits good moldability due to its thixotropic properties. Moreover, it exhibits improved adhesion to polyolefin resins without impairing the past properties. Finally, it gives rise to a cured product which is not excessively hard, with a low elastic modulus, despite filling with an inorganic compound. The composition of the present invention includes components (A) to (B) listed below and is characterized by being fluid at 25° C. and free of solvent: (A) silicone-modified polyimide resin; (B) polymerizable compound; (C) polymerization initiator, (D) hydrophobic fumed silica; and (E) adhesion auxiliary agent.

A method for conferring bacteriostatic or bactericidal properties on a surface of an object, comprising: (a) putting the surface into contact with an aqueous solution comprising an ionene-type polymer functionalised by at least one radically polymerisable function, an organic compound with two radically polymerisable functions, an organic compound with three radically polymerisable functions and a photoinitiator, (b) subjecting the surface coated with the aqueous solution to irradiation by means of which a radical polymerisation is initiated and a grafted three-dimensional polymer network comprising ionene-type polymers is obtained. The aqueous solution and the object thus obtained as well as uses thereof in particular for preparing protective garments, for packaging and/or storing fresh food products but also for purifying or decontaminating a solution or a surface.

Polyimide oligomer terminated with maleimide end groups may be cured by irradiation with UV light. The polyimide oligomer terminated with maleimide end groups may be cured in a polymerization mixture that includes a reactive diluent and optionally a photoinitiator. Due to the ability of the polyimide oligomer terminated with maleimide end groups to be cured with light applications the cured oligomer may be used in applications that require low temperatures.
