Abstract: A method to evaluate the force required to dislodge glass beads from a road marking is disclosed. The method comprises: spreading a road marking formulation onto a substrate to a pre-determined thickness, positioning glass bead(s) in the road marking layer and measuring the force required to dislodge the glass bead(s) from the road marking layer with a tensile tester. The method can be used to evaluate performance of different road marking formulations with a consistent evaluation method for all formulations, and with minimal variability for the same batch of road marking formulation.

Abstract: A composition for applying onto a road surface and methods for making thereof is disclosed. The composition comprises a binder material of at least a styrenic block copolymer and a resin, which can be pelletized. The SBC is selected from a styrene-isoprene-styrene rubber (SIS) and styrene-isoprene/butadiene-styrene (SIBS); or styrene-ethylene/propylene/styrene-styrene (SEPSS), styrene-ethylene/butylene/styrene-styrene (SEBSS) and mixtures thereof. The binder can be used in road marking compositions or surface treatment compositions when combined with other components such as pigments, glass beads, anti-skid media, fillers, waxes, elastomer/plastomer, and plasticizers.

Abstract: This invention relates to improved flexible foams prepared from polymer polyols and to a process for preparing these improved flexible foams.

Abstract: This invention relates to a process for the production of a high purity polyether carbonate polyol. The high purity polyether carbonate polyols prepared by the process herein contain a low level of catalyst residue. The process purifies polyether carbonate polyol through use of activated carbon, mixed into the polyether carbonate polyol and later removed. In addition, the activated carbon may be coated on the filter through which the polyether carbonate polyol is filtered to form the high purity polyether carbonate polyol.

Abstract: A process for transitioning a reactor from base-catalyzed polyol production to double metal cyanide (DMC)-catalyzed polyol production is described. The process includes discharging a base-catalyzed and un-neutralized product mixture from a reactor, and adding an acidified polyether polyol starter and DMC catalyst mixture to the reactor. A DMC-catalyzed polyol production reaction can then be conducted in the reactor without intermediate washing or rinsing of the reactor, and without catalyst deactivation from base or alkaline hold-up.

Abstract: This invention relates to a process for the production of a high purity polyether carbonate polyol. The high purity polyether carbonate polyols prepared by the process herein contain a low level of catalyst residues. The process adds diatomaceous earth to a polyether carbonate polyol to form a suspension, mixes the suspension for a specified time period at a specified temperature, and filters the suspension to form the high purity polyether carbonate polyol.

Abstract: This invention relates to novel polyol blends, a process for the production of foam with very low resistance to air flow from certain polyol blends and to the resultant foams produced from certain polyol blends. The polyol blends comprise one or more monofunctional polyethers having a hydroxyl number of less than 28; one or more polyether polyols having a hydroxyl number of 20 to 240 and containing at least 50% of copolymerized oxyethylene; one or more polyether polyols having a hydroxyl number of 47 to 300 and containing from 5 to 40% of copolymerized oxyethylene; and optionally, one or more polyether polyols having a hydroxyl number of 10 to 45. This process of the invention comprises reacting one or more polyisocyanates, with an isocyanate-reactive component in the presence of at least one catalyst, at least one surfactant and at least one blowing agent.
