Silanes useful as water tree and electrical tree resistant additives

Compositions of matter described as alkyl or alkenyl tris or tetrakis (phenoxyalkoxy) silanes are useful as tree retardant additives for polymeric insulation compositions. These silanes have the general formula: ##STR1## wherein R is C.sub.1 -C.sub.5 alkyl, C.sub.2 -C.sub.4 alkenyl or ##STR2## y is an integer of 1 to 5 and n is an integer of 1 to 4.

Phenoxyalkoxy silanes

4,4'-dihydroxydiphenyl ether (DHDPE) is prepared by the catalytic oxidation of 4,4'-diisopropyldiphenyl ether to the corresponding dihydroperoxide, the latter being subjected to acid cleavage to provide the desired dihydroxy compound.

Process for preparing 4,4-dihydroxydiphenyl ether

A novel, water-soluble acetal polymer is prepared by reacting a hydroxyl-containing aldehyde with a glycol in an acid reaction medium. The acetal polymer is useful as a dispersing agent for other polymers and as a reactant for the preparation of polyurethane resins.
