20. ABSTRACT (Contln 



ssary end identify by block number) 



A series of alkyd resins were prepared that had tin chemically bonded to them. These 

 resins had more resistance to fungal growth than did the original alkyd resins from which 

 they were prepared. This resistance does not appear to be lost as readily by leaching with 

 rain as that of a resin to which bis (tri-n-butyltin) oxide is added as a preservative.
