Polymerizable UV absorbers for the UV stabilization of polyesters. I. Design, synthesis and polymerization of a library of UV absorbing monomers

UV stabilizers, such as Tinuvin 1577, are organic additives that are used in the polymer industry to suppress polymer photodegradation, however leaching of the stabilizers from polymers is a significant practical issue which limits the effectiveness of the stabilizers and restricts polymer lifetimes. Novel, polymerizable UV stabilizers were synthesised and copolymerized with bis(2-hydroxyethyl) isophthalate to yield poly(ethylene isophthalate) copolymers where the UV stabilizers are bound covalently into the polymer chains. This strategy prevents leaching of stabilizers from polymers over time, and is expected to lead to enhanced UV protection of polymers compared to the admixing of polymers with UV stabilizers of low molar mass.

Methods for the preparation of tris-aryl-o-hydroxyphenyl-s-triazines

A process for preparing 2-(2,4-dihydroxyphenyl)-4.6-diaryl-s-triazines in three steps starting with cyanuric chloride is described. Step1involves the nucleophilic (basic) displacement of one chlorine atom with a phenolic moiety. Step2involves a Friedel-Crafts reaction using a Lewis acid catalyst (preferably aluminum chloride) to replace the remaining two chlorine atoms with aryl groups such as xylyl. Finally, step3involves replacing the phenolic moiety with resorcinol using either a Lewis acid or protic acid catalyst or combinations thereof. Some additional processes only peripherally related to the three-step process outlined above are also described for the preparation of various s-triazine compounds. The s-triazines prepared are useful as UV absorbers for the stabilization of organic substrates against the adverse effects of actinic light.
