Assignee:

Union Carbide Corporation - Danbury CT

International Classification:

B32B 2538
C09J 504

US Classification:

428414

Abstract:

Articles manufactured by bonding two or more shaped fiber reinforced polymeric substrates together can be made by an improved process comprising: applying a self-crosslinking acrylic polymer latex primer to the bonding surface of each of said substrates and allowing said primer to dry, applying an epoxy adhesive, in an amount sufficient to effect adhesion, to the bonding surfaces thus primed, and contacting the bonding surfaces thus primed and epoxied with one another, under conditions sufficient to cure the epoxy, to achieve bonding.

Assignee:

Union Carbide Corporation - New York NY

International Classification:

C08G 6316
C08G 6348
C08G 6376

US Classification:

260 22CB

Abstract:

There is disclosed thickened, low shrink curable molding compositions having reduced initial viscosity and the method of making the same.

Raymond C. Gandy - St. Albans WV

Assignee:

Union Carbide Corporation - Danbury CT

International Classification:

C08L 6706

US Classification:

525 27

Abstract:

A molding composition is provided which, through the use of a lactone monomer, improves the surface characteristics of the molded composite. In particular, the use of. epsilon. -caprolactone (oxepane-2-one) provides a smoother surface and enhanced dimensional stability.

Kenneth Earl Atkins - South Charleston WV

Assignee:

Union Carbide Chemicals & Plastics Technology Corporation - Danbury CT

International Classification:

C08K 549
C08F 800
C08F 2000

US Classification:

524115

Abstract:

Molding compositions comprising certain epoxy compounds, at least one antioxidant, an unsaturated thermosetting resin and an olefinically unsaturated monomer are disclosed. The disclosed compositions can provide enhanced yellowing resistance to articles molded from the compositions, particularly when the molding compositions contain white pigment. Processes from molding articles having enhanced yellowing resistance are also disclosed.

Appl. No.:

7/799727

Inventors:

Kenneth E. Atkins - South Charleston WV

Assignee:

Union Carbide Chemicals & Plastics Technology Corporation - Danbury CT

International Classification:

C08L 6706
C08K 714

US Classification:

523523

Abstract:

A molding composition comprises a) an unsaturated polyester resin, b) a copolymerizable olefinically unsaturated monomer, c) a pigment, d) fiber reinforcement and e) a poly(vinyl ether) polymer with a weight average molecular weight of at least 50,000 to control shrinkage and promote the uniform distribution of the pigment in the molding composition.

Appl. No.:

6/602635

Inventors:

Kenneth E. Atkins - South Charleston WV

Assignee:

Union Carbide Corporation - Danbury CT

International Classification:

C08K 322

US Classification:

523515

Abstract:

There is disclosed thickened, low shrinkage polyester molding compositions having improved pigmentation. The improved pigmentation in thickenable polyester molding compositions is achieved by using as the low profile additive a vinyl acetate/maleic acid copolymer, and optionally incorporating a surfactant in the composition.

Assignee:

Union Carbide Chemicals & Plastics Technology Corporation - Danbury CT

International Classification:

C08L 7504
C08L 6706

US Classification:

525 28

Abstract:

Polyurethanes having utility, for example, as low profile additives, in polyester-based molding compositions, a method of preparing polyester-based molding compositions containing such polyurethane low profile additives and thermoset articles made with the method are disclosed. The disclosed polyurethane low profile additives can enhance the pigmentability of molded articles comprising the low profile additives. The low profile additives comprise the reaction product of a hydroxyl-terminated prepolymer and an anhydride such as a dicarboxylic acid anhydride, preferably reacted in the presence of a catalyst comprising an amine having from about 4 to 20 carbon atoms.
