The invention provides a method of sustained delivery of a lactam, imide, amide, sulfonamide, carbamate or urea containing parent drug by administering to a patient an effective amount of a prodrug compound of the invention wherein upon administration to the patient, release of the parent drug from the prodrug is sustained release. Prodrug compounds suitable for use in the methods of the invention are labile conjugates of parent drugs that are derivatized through carbonyl linked prodrug moieties. The prodrug compounds of the invention can be used to treat any condition for which the lactam, imide, amide, sulfonamide, carbamate or urea containing parent drug is useful as a treatment.

The present invention provides:
a resin composition for use in a liquid sealant,
which is composed mainly of an epoxy compound and a polycarbodiimide resin, the proportion of the polycarbodiimide resin being 0.1 to 10 parts by weight relative to 100 parts by weight of the epoxy compound, and which is liquid or fluid at ordinary temperature; and
a liquid sealant comprising:
a resin composition which is composed mainly of an epoxy compound and a polycarbodiimide resin, the proportion of the polycarbodiimide resin being 0.1 to 10 parts by weight relative to 100 parts by weight of the epoxy compound,
an epoxy resin curing agent,
an epoxy resin curing accelerator, and
an inorganic powder,
which liquid sealant is liquid or fluid at ordinary temperature.

The present invention provides a resin composition having an oxygen scavenging function. The resin composition comprises 70 to 99.9 wt% of a polyvinyl alcohol resin (A) and 0.1 to 30 wt% of a thermoplastic resin (B) other than the polyvinyl alcohol resin (A), wherein the thermoplastic resin (B) has a carbon-carbon double bond and a functional group including a hetero atom, and an oxygen absorption rate of the resin composition is 0.001 ml/m2 • day or more.
An objective of this invention is to provide a silicone resin composition giving a silicone cured rubber exhibiting a higher elongation percentage as well as improved heat resistance, oil resistance and chemical resistance, which are particularly required for automobile applications. A silicone cured rubber meeting the above physical property requirements can be prepared by moisture-curing a silicone resin composition including 100 wt parts of (a) an OH-containing polysiloxane, 0.1 to 200 wt parts of (b) a carbodiimide and (c) an organosilicon crosslinking agent, or alternatively by thermally curing a silicone resin composition including 100 wt parts of (a) an OH-containing polysiloxane, 0.1 to 200 wt parts of (b) a carbodiimide and (d) an amino-containing silane.
