Abstract: Starch lactide derivatives and the preparation of such derivatives wherein starch is reacted with lactide in an aqueous caustic media. Another embodiment involves the extrusion of the starch lactide derivatives to form starch based foam products having increased flexibility, strength and compatibility.

Abstract: A thickened aqueous fabric softener composition comprising at least one surfactant and a polymeric rheology modifier, wherein said polymeric rheology modifier is the polymerization product of (i) an alkyl ester of acrylic acid or methacrylic acid; (ii) a monomer selected from the group consisting of a vinyl-substituted heterocyclic compound containing at least one nitrogen or sulfur atom, (meth)acrylamide, a mono- or di-alkylamino alkyl(meth)acrylate, and a mono or di-alkylamino alkyl(meth)acrylamide; and (iii) an associative monomer. The polymeric rheology modifier does not require a make down step to slurry or disperse it into a fabric softener composition. The thickened fabric softener compositions do not affect rewettability, nor do they build up on cloth in multi-cycle washing. In addition, the thickened fabric softener compositions provide softening and reduce the formation of wrinkles.

Abstract: Epoxy compositions having improved toughness and flexibility comprising a polyepoxide of the formula ##STR1## wherein each X is H, allyl or glycidyl, Y is allyl or glycidyl and R is an alkyl of 1 to 4 carbons with there being at least two epoxy groups on the ring modified with a carboxy terminated polymer.

Abstract: This invention presents a series of glasses which possess low softening points, high resistance to recrystallization and good durability in the presence of moisture. The glasses are contained within oxides of silver, vanadium, tellurium, and lead and have glass transition temperatures below 260.degree. C., and are useful in electronic applications such as die attach adhesives and sealing glasses.
