ABSTRACT:
Hydroxy-t-akyl peroxyesters having the general structure ##STR1## where R, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 can be alkyl moieties and having 10 hour half-life temperatures below about 75.degree. C. (for example, 3-hydroxy-1,1-dimethylbutyl peroxyneodecanoate) are used as initiators for vinyl monomer polymerization and as catalysts for curing unsaturated polyester resins in order to improve the efficiency of the systems.
