摘要:
The invention relates to the radical cold-curing of synthetic resins based on poIy(meth)acrylate-urethane-(meth)acrylates in urethane(meth)acrylates and optionally (meth)acrylates and/or reactive thinners, using suitable additives, in addition to the use of said radically cold-curing synthetic resins as binding agents in radically cold-curing mixtures and to organic synthetic glass, plastics, synthetic glass or plastic workpieces and composite materials and composite workpieces obtained from said mixtures by radical cold-curing. The invention also relates to the production and use of said mixtures, organic synthetic glass and plastics, synthetic glass or plastic workpieces and composite materials and composite workpieces.
摘要:
The invention relates to an actuator for converting between mechanical and electrical energy comprising - at least two electrodes; and - an electroactive polymer, comprising aromatic moieties in the chain and flexible moieties in the chain, the polymer further comprising side groups bound to the chain, which side groups are selected from the group consisting of polar side groups and side groups comprising an aromatic moiety. The invention further relates to a novel electroactive polymer comprising side groups bound to the chain, which side groups are selected from the group consisting of polar side groups and side groups comprising an aromatic moiety.
摘要:
An energy-core ink or varnish composition is provided for use in an in-mold decoration (IMD) process, comprising an energy-curable resin, additional reactive monomers and/or oligomers and, optionally and in an amount not exceeding 10% by weight, a solvent, wherein the resin comprises a urethane acrylate oligomer having an aromatic or aliphatic polycarbonate backbone. For inks, the composition additionally includes a pigment or dye. For photocure compositions, a photoinitiator is also included. Also provided is an in-mold decoration (IMD) process employing the ink or varnish composition.
