摘要
(US9416271) A method for forming a halogen-free curable composition containing a benzoxazine monomer, at least one epoxy resin, a catalyst, a toughening agent and a solvent.  The halogen-free curable composition is especially suited for use in automobile and aerospace applications since the composition, upon curing, produces a composite having a high glass transition temperature.

(US9416271) 1. A method for producing a halogen-free curable composition comprising mixing together: (a) a benzoxazine monomer of the formula (I) wherein each R is, independently from one another, allyl, unsubstituted or substituted phenyl, unsubstituted or substituted C1-C8-alkyl or unsubstituted or substituted C3-C8 cycloalkyl; (b) at least one epoxy resin; (c) 5.7-10 parts by weight per 100 parts by weight of the composition of a catalyst selected from tetraphenolethane; (d) 5.7-10 parts by weight per 100 parts by weight of a toughening agent of the formula (II) wherein m is 1 or 2, n is 2 to 6, R0 is an n-valent radical of an elastomeric prepolymer after the removal of the terminal isocyanate, amino or hydroxy l groups, the elastomeric prepolymer being soluble or dispersible in epoxy resin, X and Y independently of one another are -- O -- or -- NR3 -- , at least one X or Y being -- NR3 -- , R2 is an m+1-valent radical of polyphenol or aminophenol after the removal of the phenolic hydroxy l group(s) and optionally of the amino group, and R3 is hydrogen, C1-C6 alkyl or phenol; and (e) a solvent to produce the halogen-free curable composition. 4. A method of forming an article comprising: (a) applying on a first substrate a halogen-free curable composition comprising (i) a benzoxazine monomer of the formula (I) wherein each R is, independently from one another, allyl, unsubstituted or substituted phenyl, unsubstituted or substituted C1-C8-alkyl or unsubstituted or substituted C3-C8 cycloalkyl; (ii) at least one epoxy resin; (iii) 5.7-10 parts by weight per 100 parts by weight of the composition of a catalyst selected from tetraphenolethane; (iv) 5.7-10 parts by weight per 100 parts by weight of a toughening agent of the formula (II) wherein m is 1 or 2, n is 2 to 6, R0 is an n-valent radical of an elastomeric prepolymer after the removal of the terminal isocyanate, amino or hydroxy l groups, the elastomeric prepolymer being soluble or dispersible in epoxy resin, X and Y independently of one another are -- O -- or -- NR3 -- , at least one X or Y being -- NR3 -- , R2 is an m+1-valent radical of polyphenol or aminophenol after the removal of the phenolic hydroxy l group(s) and optionally of the amino group, and R3 is hydrogen, C1-C6 alkyl or phenol; and (v) a solvent; (b) adjoining a second substrate to the first substrate; and (c) heating the halogen-free curable composition and substrates at a temperature greater than 150 deg. C. to adhere the substrates together and form the article. 5. A container comprising a halogen-free curable composition wherein the halogen-free curable composition comprises (a) a benzoxazine monomer of the formula (I) wherein each R is, independently from one another, allyl, unsubstituted or substituted phenyl, unsubstituted or substituted C1-C8-alkyl or unsubstituted or substituted C3-C8 cycloalkyl; (b) at least one epoxy resin; (c) 5.7-10 parts by weight per 100 parts by weight of the composition of a catalyst selected from tetraphenolethane; (d) 5.7-10 parts by weight per 100 parts by weight of a toughening agent of the formula wherein m is 1 or 2, n is 2 to 6, R0 is an n-valent radical of an elastomeric prepolymer after the removal of the terminal isocyanate, amino or hydroxy l groups, the elastomeric prepolymer being soluble or dispersible in epoxy resin, X and Y independently of one another are -- O -- or -- NR3 -- , at least one X or Y being -- NR3 -- , R2 is an m+1-valent radical of polyphenol or aminophenol after the removal of the phenolic hydroxy l group(s) and optionally of the amino group, and R3 is hydrogen, C1-C6 alkyl or phenol; and (e) a solvent.
