Abstract: This invention relates to novel .alpha.-lower alkoxy-o-cresyl carbamates having utility as insecticides and polymer intermediates.

Abstract: Brominated carbamoyl derivatives of the structure:R.sub.2 N -- C(O) --O--(R.sup.1).sub.n -- CH.sub.2 --C (X).sub.2 --CH.sub.2 -- (R.sup.1).sub.n --O--C(O)NR.sub.2wherein:R is independently selected from the group consisting of hydrogen, alkyl, alkanol, cycloalkyl of from 5 to 7 carbon atoms, phenyl, alkyl substituted by phenyl, phenyl substituted by alkyl, hydroxy terminated oxyalkylene, hydroxy substituted hydroxy terminated oxyalkylene and halogen substituted hydroxy terminated oxyalkylene;R.sup.1 is independently selected from the group consisting of alkylene; oxyalkylene, hydroxy substituted oxyalkylene, halogen substituted oxyalkylene and alkylene or oxyalkylene substituted by the group -- O -- C(O)NR.sub.

Abstract: Compounds of the formula: ##STR1## wherein R' is selected from the group consisting of .sup.- OH, alkyloxy and aryloxy; and R is selected from the group consisting of ##STR2## wherein Z is .sup.- OH, alkyl, aryl, alkoxy and aryloxy, provided when R' is .sup.- OH, ##STR3## are disclosed, having utility as metal ion sequestrants and flame retardant additives.

Abstract: New compounds are disclosed of the formula: ##STR1## wherein R' is phenyl, lower alkenyl and halogen substituted and unsubstituted lower alkyl of 1-6 carbon atoms, m is an integer from 1-2 wherein when m is 2, R is alkoxy of 1-8 carbon atoms and when m is 1, R is alkylene dioxy of 2-8 carbon atoms. The compounds of this invention are useful as flame retardant agents for textile materials and in the production of polymers and copolymers which possess flame retardant properties.
