OUTDOOR DURABLE COATING COMPOSITIONS AND ACID FUNCTIONAL POLYESTER RESINS AND POLYGLYCIDYL ESTERS THEREOF USABLE THEREFOR

摘要

Tertiary carboxyl functional polyester resin is prepared by reacting an aliphatic compound (I) containing two primary or secondary alcohol groups and a tertiary carboxyl group with a cycloaliphatic compound (III) containing two aliphatic carboxyl or anhydride groups. The reaction may also include another compound (II) containing two primary or secondary alcohol groups, and/or another acid (IV) containing two aliphatic carboxyl or anhydride groups, and/or a compound (V) containing one primary or secondary alcohol group and a tertiary carboxyl group or a monocarboxylic acid (VI) containing a primary or secondary carboxyl group used with an equivalent amount of a primary or secondary alcohol (VII). The molar ratio of (I) + (II):(III) + (IV):(V):(VI):(VII) = 1-13:2-14:0-2:0-2:0-2.
