摘要:
Resinous compositions comprising an acrylic resin containing, as polymer constituting units, 20 to 55% by weight of tri-organic tin .alpha.,.beta.-unsaturated carboxylate, 0.1 to 25% by weight of hydroxy bearing (meth)acrylate and the remainder of another polymerizable unsaturated monomer are provided. The compositions are useful as resinous vehicles for antifouling paints, capable of being gradually hydrolyzed in sea water, thereby resulting in a smooth coating surface and liberating an antifouling agent by themselves.

摘要:
Preparation of hydrolyzable polyester resin comprising reacting polycarboxylic acid and polyhydric alcohol components, which is characterized by using, as at least part of said polyhydric alcohol component, a metallic salt of hydroxy carboxylic acid of the formula defined and effecting the polycondensation at a temperature which is no more than the decomposition temperature of said metallic salt. The polyester resins are useful as resinous vehicle of varnishes and antifouling paints.
摘要:
A method for preventing settlement of aquatic fouling organisms on surface of an aquatic structure without environmental hazard is provided. The method is based upon absolutely novel concept to prevent the settlement by means of thick slime layer, i.e. bio-jelly, deposited on said surface. The present invention also provides a bio-jelly producing agent and a bio-jelly producing paint both useful for the present method. Further, the present invention provides a novel low toxic antifouling agent.
摘要:
The present invention is related to a resin for use in an antifouling coating which is a polymer obtained by polymerizing a polymerizable unsaturated monomer(s) and having, at side chain terminals thereof, a trisubstituted borane-amine complex and an azomethine group, or a group represented by the following general formula (1): (wherein M represents a metal selected from the group consisting of copper, zinc, nickel and cobalt, - - - means a chemically bound state, W represents —N(R1)R2— (in which R1 and R2 may be the same or different and each represents a hydrogen atom or an alkyl group containing 1 to 4 carbon atoms), —OCO—, —OSO2— or L represents an alkylene group containing 1 to 4 carbon atoms, and m represents an integer of 0 to 4).
摘要:
An antifouling paint containing a copolymer including a recurring unit of the formula: ##STR1## wherein R.sup.1 is hydrogen atom, methyl or an alkoxycarbonyl, R.sup.2 is hydrogen atom or an alkoxycarbonyl, A is an acid ion-terminated pendant group, M is a transitional metal ion, L is a monobasic organic acid ion, and m is the valency of the transitional metal M; and an amount of an organic ligand capable of coordinating to the transitional metal. The ion-association and reactivity of the metal in the copolymer may be retarded by complexing with the organic ligand in situ.
摘要:
A bioactive substance control-releasing resinous composition comprising a resin having main chain and side chains, at least one side chain bearing at the end portion thereof an organic acid moiety having a biological activity, through a metal ester bonding. The resin is hydrolyzed in an ionic atmosphere at a controlled rate to generate a bioactive substance as well as metal ions and is useful in various fields and especially as a resinous vehicle for a coating composition.
