摘要:
The present invention discloses catalyst compositions for producing polyurethane products having improved heat and humid aging properties and to processes for the manufacture of polyurethane products using such catalysts. The catalysts are based on a blend of at least one compound having a tertiary amine and isocyanate reactive group and at least one compound having a quaternary ammonium alkoxide moiety and at least one tertiary amine group wherein the later compound is partially or completely neutralized with at least one acidic compound.
摘要:
The present invention pertains to low emission polyurethane polymer products based on autocatalytic polyols made by modification of conventional polyols with tertiary amines and processes for their manufacture. The tertiary amine is bound to a conventional polyol by means of an epoxide, epichlorohydrin, or grafting by means of an azo and/or peroxide initiator or sulfonyl azide.
摘要:
A flasher module, installable on a ladder, incorporates multiple high-intensity light-emitting diodes (LEDs), which are coupled to an electro-chemical power source (battery or single cell). The LEDs may be wired for a continuous “ON” condition, but are preferably connected to flasher circuitry. For maximum visible intensity, the flasher circuitry is designed so that all LEDs flash simultaneously about one to two times per second. A first embodiment flasher module is sized to install within the uppermost portion of a ladder rail of C-shaped cross section. A second embodiment module, which provides a larger viewing angle, incorporates the LEDs within a bar that is mountable beneath the uppermost rung of the ladder. Either embodiment of the invention may be equipped with a gravity-actuated switch, which will turn on the flasher circuitry whenever the ladder is deployed at an angle greater than 45 degrees from horizontal.

摘要:
Copolymers having repeating units derived from monocyclic esters or carbonates and certain bicyclic diesters and/or carbonates have controllable rheological properties. The bicyclic diester and/or carbonate copolymerizes easily with the monocyclic monomers, especially with lactide, to form copolymer that can have tailored levels of branching. The copolymers have excellent rheological properties, including increased melt tensions and improved shear thinning, compared to the analogous linear polymers.
