Abstract: This invention is directed to a stabilizer useful to retard transesterification in moldable polymer blends containing polyester(s) during processing of the blends at elevated temperatures, particularly at high temperatures above about 285.degree. C. More particularly, the stabilizer comprises a phosphate-epoxy adduct. The stabilizer may optionally further comprise a reactive functionality component comprising a compound having a imide or oxazoline functionality and/or a hindered phenol component. The invention is also directed to a composition comprising the stabilizer and a particularly defined polymer blend.

Abstract: Compounds having the formula: ##STR1## wherein T is a polycycloalkylidene group (e.g., adamant-2-ylidene); R is a C.sub.1-20 alkyl, aralkyl or cycloalkyl group; and Y is a fluorescent chromophore (e.g., m-phenylene), produced by reacting a compound having the formula: ##STR2## with an R-ylating agent (e.g., R.sub.2 SO.sub.4) in the presence of an alkali metal alkoxide in a polar aprotic solvent. Also, compounds having the formula: ##STR3## are produced by reacting a compound having the formula: ##STR4## wherein X is an electronegative leaving group (e.g., a halogen anion such as chloride ion) in the presence of a Lewis base (e.g., a trialkyl-amine) dissolved in an aprotic organic solvent (e.g., benzene or toluene). Also, compounds having the formula ##STR5## are produced by reacting a compound of the formula ##STR6## with a tetra-O-acylated-O-hexopyranoside halide, then hydrolyzing off the protective acyl groups.
Abstract: A process for producing a polyfunctional cyanate ester polymer which comprises heating at least one polyfunctional cyanate ester compound having the formula:R--OCN).sub.mwherein m is an integer of at least 2 and R is one or more aromatic organic groups, and the cyanato groups are bonded to the arylene ring, in the presence of a catalytic amount of a dialkyl tin oxide having the formula:R.sup.1 R.sup.2 SnOwherein each of R.sup.1 and R.sup.2 is C.sub.1 -C.sub.30 alkyl is disclosed.
Abstract: Oximinophosphoric acid derivatives of the formula ##STR1## where R.sup.1 is a straight-chain or branched alkyl of not more than 4 carbon atoms, R.sup.2 is a straight-chain or branched alkoxy or alkylthio group of not more than 4 carbon atoms, straight-chain or branched alkyl of not more than 3 carbon atoms, phenyl, amino or a straight-chain or branched alkylamino or dialkylamino radical, where alkyl in each case is of not more than 4 carbon atoms, and X is oxygen or sulfur, a process for the manufacture of these oximinophosphoric acid derivatives, and their use for controlling pests.
