Provided is an antifouling coating composition, which can form a coating film having good hardness and good physical properties and having a wear degree appropriate for expressing a long-term antifouling effect, has a viscosity not being excessively high, and makes it possible to reduce a content of volatile organic compounds, and a polymer-containing composition which is suitable for obtaining the antifouling coating composition. The polymer-containing composition contains a (meth)acryl-based copolymer (A-1), in which the (meth)acryl-based copolymer (A-1) contains a constitutional unit (U11) or a constitutional unit (U12) having carboxylate forming an ionic bond with a divalent metal atom, and has a weight-average molecular weight of 1,000 to 5,000, and the polymer-containing composition has a coating film hardness (Martens hardness) equal to or higher than 2.5 N/mm.

Polymer-containing composition and antifouling coating composition

First embodiment of a (meth)acrylic copolymer in the present invention includes following: a (meth)acrylic copolymer having at least one kind of constitutional unit selected from the group consisting of a constitutional unit (A1) having at least one kind of structure (I) selected from the group consisting of structures represented by the following formula (1), formula (2), or formula (3) and a constitutional unit (A2) having a triorganosilyloxycarbonyl group and a constitutional unit (B) derived from a macromonomer (b): 

(Meth)acrylic copolymer, polymer solution, polymer-containing composition, anti-fouling coating composition, and method for producing (meth)acrylic copolymer

A (meth)acrylic copolymer of the present invention includes a constituent unit (B) derived from a polysiloxane block-containing polymerizable monomer (b) represented by Formula (b1). In Formula (b1), Rrepresents a hydrogen atom or a methyl group, a represents an integer of 2 to 5, b represents a number of 0 to 50, c represents an integer of 0 to 18, d represents a number of 1 to 1000, e represents a number of 1 to 80, Rto Reach represents an alkyl group, an alkoxy group, a phenyl group, a substituted phenyl group, a phenoxy group, or a substituted phenoxy group.

(meth)acrylic copolymer, method for producing same, resin composition and antifouling paint composition

A (meth)acrylic copolymer of the present invention includes at least one constituent unit (A) selected from the group consisting of a constituent unit (A1) having at least one structure (I) represented by Formula (1), Formula (2), or Formula (3), a constituent unit (A2) containing a triorganosilyloxycarbonyl group, and a constituent unit (A3) having at least one structure (III) represented by Formula (4) or Formula (5), a constituent unit (B) derived from a specific polysiloxane block-containing polymerizable monomer (b), and a constituent unit (C) derived from a macromonomer (c).

Resin composition with a (meth)acrylic copolymer, antifouling paint composition, and method for producing same

A plated plated fiber-reinforced member includes: a fiber-reinforced member formed of a composite fiber material in which multiple reinforcing fibers dispersed in a resin, some of the multiple reinforcing fibers being allowed so that portions thereof protruding from a surface of the resin; and an electroless-plated layer formed on the fiber-reinforced member to cover the surface of the resin and the portions of the reinforcing fibers protruded from the surface of the resin.
