Embodiment

[0071] The polymers of the present invention were synthesized from the monomers in the ratios and amounts listed in Tables 1, 2, 3 and 4 in the following manner. Comparative polymers are also listed in those tables. A total of 54 different polymers were synthesized and reported in Tables 1, 2, 3 and 4.

[0072] resolve resolution:

[0073] A 250 mL three necked round bottom reaction flask equipped with a dry ice condenser, addition funnel and thermometer was placed under nitrogen. Half of the total volume of degassed anhydrous meta-xylene was transferred to the reaction flask under nitrogen, and the liquid was stirred and heated to 85 ± 2 °C.

[0074] In a 250 mL Erlenmeyer flask, add the remaining volume of anhydrous m-xylene, fluorinated monomer, silylated monomer, any other comonomers, and azoisobutyronitrile (AIBN, see Table 1) to prepare monomer batches. The monomer batch was capped and nitrogen was bubbled through the resulting solution for 10 minutes. The monomer b...

Abstract

Copolymers of at least three monomer units selected from the group consisting of fluorinated acrylic (methacrylic) monomers, triorganosilylacrylic (e.g. trimethylsilyl methacrylate) monomers and acrylic monomers not containing an organosilyl moiety, (e.g. methyl methacrylate) and optionally containing from 0-5 weight percent of a cross-linking agent are novel compositions useful as polymeric binders in long life marine antifoulant coatings. The erosion rate and resistance to cracking of the copolymer of the present invention when used as a binder in a marine antifoulant paint is controlled by adjusting the proportions of each monomer and the amount of crosslinking agent in the copolymer of the present invention.

Description

technical field [0001] The invention relates to an antifouling composition, in particular to a marine antifouling paint composition. Background technique [0002] Marine organisms such as seaweed and barnacles cling to the surfaces of structures in oceans and lakes. These marine organisms have little effect on eg steamships, boats, pilings, intake and discharge (coated) pipes. (Worms and borers eat wood and plastic). However, their presence can severely hamper the operation of these systems, resulting in loss of heat dissipation and fuel efficiency. It is often practical to coat wood, plastic and metal substrate surfaces with coating compositions that inhibit the attachment and / or growth of marine organisms. Such coating compositions are generally referred to as antifouling paints or antifouling paints, and consist of polymeric binder materials, poisons, pigments, solvents and adjuvants to aid in adhesion, flow, coloration, viscosity and stability, among others. The rang...
