Abstract: Novel resins, useful as strengthening resins for imparting dry and temporary wet strength to paper, are disclosed. The resins are prepared by reacting branched water-soluble poly(.beta.-alanine) with glyoxal.

Abstract: Disclosed are brominated azido fire-retardants having the formula(Br).sub.x --R--[(R').sub.n --A].sub.ywhere R is an organic radical; R' is selected from ##STR1## where R" is selected from alkylene, cycloalkylene, alkylene cycloalkylene, arylene, alkylene arylene, and the foregoing radicals with bromo substituents, and b is an integer from 1 to 10; A is selected from ##STR2## and --SO.sub.2 N.sub.3 where z is 0 or 1; x is at least 3; n is 0 or 1; and y is an integer from 1 to 100. Also disclosed is the process of preparing fire-retardant natural and synthetic fibers and films which comprises contacting the surface of said fiber or film with a brominated azido fire-retardant and initiating reaction of the fire-retardant with the fiber or film by heat or irradiation.

Abstract: It has been found that plant viruses and viroids can be inhibited by treating plants infected with or exposed to viruses or viroids with a virus-inhibiting amount of a maleic acid, maleic anhydride or fumaric acid copolymer.

Abstract: Disclosed are epoxy-azido compounds of the formula ##EQU1## WHERE R is a polyvalent organic radical, R' is a hydrogen, alkyl, cycloalkyl, aryl, or aralkyl radical, A is ##EQU2## and n and m are integers from 1 to 100. Also disclosed is the use of said epoxy-azido compounds in modifying polymers, cross-linking polymers, and adhering polymers to certain substrates, e.g. glass and other polymers.

Abstract: Disclosed is a process of improving the adhesion of polyester material to various other materials using the azidoformates of omega-hydroxyalkyl phthalates, their related low molecular weight condensation polymers and their mixtures represented by the general formula ##SPC1##Where R is an alkylene radical containing 2 to 10 carbon atoms and x is an integer of from about 1 to about 10. In particular, there is disclosed a process of improving the adhesion of polyester tire cord to rubberr tire stock using the said azidoformate compounds.
