Synthesis of marine resin by graft copolymerization of some acrylic monomers onto chlorinated rubber : part II

Abstract EN

Some marine resins were prepared by graft copolymerization of butyl acrylate (BuA) and methacrylic acid (MAA) onto chlorinated rubber (CLR) in cyclohexanone using benzoyl peroxide (BPO) as free radical initiator.

The prepared copolymers were characterized by infrared spectra (FT-IR) and proton nuclear magnetic resonance (1H-NMR).

The grafted resins obtained were incorporated in the antifouling paint formulations as marine binders free from TBT, and their physical and mechanical properties were investigated.

The results revealed that the water uptake by the coatings was found to depend on the hydrophilic or hydrophobic properties of the biocides used in the formulations.

Raft test performed at Obhor Bay, Red Sea, in Saudi Arabia, showed that the surfaces of the testing panels of some formulations are not affected by marine organisms after one year of immersion.
