| abstract | (57) [Summary]nEpihalohydrin, in the presence of a base, (a) at least one aromatic or cycloaliphatic dicarboxylic acid compound A containing two aromatic or secondary aliphatic carboxyl groups or an anhydride thereof; At least one diol compound B comprising two aliphatic hydroxyl groups which may be independently primary or secondary hydroxyl groups, and optionally (c) one monofunctional primary or secondary hydroxyl group A compound comprising C1 and / or at least one compound C2 comprising one primary or secondary hydroxyl group and one tertiary aliphatic carboxyl group, and optionally (d) a tertiary aliphatic carboxyl group; A dihydroxymonocarboxylic acid compound D comprising two aliphatic hydroxyl groups, each independently being a primary or secondary hydroxyl group, and optionally (e) a trihydroxyalkane (E ) Or tetrahydroxyalkane (E2) with the molar ratio of compound A: B: C1: C2: D: E1: E2 being X + Y + 1: X: M: N: Y: Z: Q (M + N is 0 to 2) , X is 2-8, Y is 0-8, Z is 0-2, Q is 0-2), at a temperature of 100-220 ° C, the non-tertiary carboxyl initially present in the reaction mixture. An epoxy-functional polyester resin (II), obtained by reacting with a carboxyl-functional polyester resin (III) having a WPE of 250-800, obtained by reacting until essentially all of the groups have reacted, Obtained by a process comprising reacting with a carboxy-functional polyester resin derived from components (a) and (b) as described above, or with component (a) alone in the presence of a catalyst. , There is storage stable at temperatures up to 40 ° C., has a Tg temperature than 40 ° C., epoxy functional polyester resin (I) and outdoor durable coating compositions comprising the same. |
