Abstract
Antifouling resins and methods for the production of an antifouling resin comprising reacting (i) a base resin (A) simultaneously comprising a carboxyl group and a group having a polyalkylene glycol structure represented by the formula (I) [Parenopenst]CmH2mO[Parenclosest]n R1 (I) wherein R1 is a hydrogen atom or a straight chain, branched, or cyclic alkyl group or an aralkyl group, m is 1, 2, 3, or 4, and n is an integer of not less than 1 and not more than 100 in the molecular unit, with (ii) the oxide or hydroxide of a metallic atom having a valence of not less than 2 in the presence of present water in an amount of 1-30 wt. %, based on the weight of said base resin (A).
Claims13
A method for the production of an antifouling resin comprising reacting (i) a base resin (A) simultaneously comprising a carboxyl group and a group having a polyalkylene glycol structure represented by the formula (I)
- [Parenopenst]CmH2mO[Parenclosest]n R1 (I)
- wherein R1 is a hydrogen atom or a straight chain, branched, or cyclic alkyl group or an aralkyl group, m is 1, 2, 3, or 4, and n is an integer of not less than 1 and not more than 100 in the molecular unit,
- with (ii) the oxide or hydroxide of a metallic atom having a valence of not less than 2 in the presence of water in an amount of 1-30 wt. %, based on the weight of said base resin (A).
An antifouling coating composition comprising as an active component an antifouling resin obtained by reacting (i) a base resin (A) simultaneously comprising a carboxyl group and a group having a polyalkylene glycol structure represented by formula (I)
- [Parenopenst]CmH2mO[Parenclosest]n R1 (I)
- wherein R1 denotes a hydrogen atom or a straight chain, branched, or cyclic alkyl group or aralkyl group, m denotes 1, 2, 3, or 4, and n denotes an integer of not less than 1 and not more than 100 in the molecular unit, with (ii) the oxide or hydroxide of a metallic atom having a valence of not less than 2 in the presence of water present in an amount of 1-30 weight %, based on the weight of said base resin (A).
