ABSTRACT:
Compositions for improving the weatherability of synthetic resins are prepared by modifying an epoxy resin with at least one acid selected from the group consisting of cinnamic acid, .alpha.-methylcinnamic acid and o-coumaric acid. The addition of such agents to synthetic resins provides a resulting resin which has improved weatherability, transparency and thermal stability.
