A new primer for electroless plating for use in the pretreatment process for electroless plating, which is environmentally friendly, can be easily treated in fewer process steps, and can provide sufficient adhesion to the substrate. A photocurable primer for forming a metal plating film on a base material through an electroless plating process, having (a) a hyperbranched polymer having an ammonium group at a molecular terminal and a weight average molecular weight of 1,000 to 5,000,000, (b) metal fine particles, (c) a polymerizable compound having a (meth)acryloyl group, and (d) a photopolymerization initiator.

The present invention provides, inter alia, a process for incorporating a cyclopropenium ion into a polymeric system. Processes for making cross-linked polymers, linear polymers, and dendritic polymers, as well as for incorporating a cyclopropenium ion onto a preformed polymer are also provided. Further provided are stable, polycationic compounds, various polymers that contain stable cyclopropenium cations, and substrates containing such polymers. The use of these polymers in water purification systems, antimicrobial coatings, ion-transport membranes, cell supports, drug delivery vehicles, and gene therapeutic vectors are also provided.

The invention provides UV-sensitive monomers, comprising a cyclopropenone-containing group, which acts as a masked dibenzocyclooctyne (DBCO)/dibenzoazocyclooctyne (DIBAC) group. The monomers of the invention can be polymerized for example via reversible addition fragmentation chain transfer (RAFT) polymerization techniques to yield a polymer comprising the masked DBCO/DIBAC group. In certain embodiments, the DBCO/DIBAC group can be unmasked under controlled conditions, allowing conjugation of small molecules and/or macromolecules to the polymer through highly selective and efficient strain-promoted azide alkyne click chemistry (SPAAC).

Provided is a dope used when a film containing an acrylic-based resin and a core-shell type graft copolymer is made by a solution casting method, in which turbidity is less likely to occur despite the use of a core-shell type graft copolymer having a core layer with a large particle diameter. A dope for producing a film by a solution casting method contains a thermoplastic acrylic-based resin, a graft copolymer, and a solvent. In this dope, the graft copolymer has a core layer and a shell layer, the core layer has an average particle diameter of 125 to 400 nm, the graft copolymer has a degree of swelling by methyl ethyl ketone of 3.5 or more, and the solvent has a hydrogen bonding term δH in a Hansen solubility parameter of 6.0 or more and 8.0 or less.
