Title: Preparation of polyetherpolyols from polysaccharides, useful in polyurethane production involves addition of alkylene oxides to polysaccharides, previously reacted with phosphorus oxychloride
Inventor: MEERBOTE MICHAEL
IPC: C08L71/02
Filed: 1999-05-29
Abstract: Polyurethane foams can be prepared from polyetherpolyols without additional catalysts and activators.  polyurethane foams can be prepared from polyetherpolyols without additional catalysts and activators. Polyetherpolyols of OH number 250-500 are prepared by addition of 2-4C alkylene oxides to polysaccharides in the presence of preferably alkaline catalysts. In an introduced reaction step polysaccharide with phosphorus oxychloride is reacted with the total amount of the required C3/C4 alkylene oxide mixture, or with a propylene oxide/ethylene oxide mixture of ethylene oxide content 10-60 wt.% on the total alkylene oxide content, with subsequent alkoxylation at 60-100 deg C. The polyetherpolyol obtained is then reacted directly with diisocyanates without catalyst addition to give polyurethane foams.

Abstract: The invention provides a device with an improved tunable laser
structure, the structure useful with surface emitting lasers and capable
of exhibiting desirable latchability. The tunable laser of the invention
contains a laser structure having a lower reflector (16), an active
laser region (12), and an upper reflector (14). The upper reflector
contains a non-moveable reflector portion located adjacent the active
laser region and a moveable reflector portion located a spaced distance
(20) from the non-moveable reflector portion. A magnetic material (22)
is located either on a surface of the moveable reflector portion or on a
surface in contact with the moveable reflector portion, and a
programmable magnet (24) is located near the magnetic material, the
magnet capable of inducing controlled movement of the magnetic material.
This movement in turn induces movement of the moveable reflector portion
such that the spaced distance (20) between the moveable reflector
portion and the non-moveable reflector portion is capable of being
adjusted. By adjusting this spaced distance (i.e., the air gap between
the moveable and non-moveable reflector portions), the phase of
reflection and thus the laser output wavelength is controlled.
