Patent number: 4497913Abstract: A stable dispersion of a polymer in a polyol is prepared by reacting an organic polyisocyanate with a short-chain polyol in a high molecular weight polyol containing a relatively high primary hydroxyl group content, the ratio of the content of primary hydroxyl groups in the short-chain polyol to that in the high molecular weight polyol being at least a critical lower limit of about 3.5. The reaction is further carried out in the presence of a small proportion of water to achieve a reduction in the viscosity of the resulting dispersion. The dispersion is used in preparing high resilience polyurethane foam having desirable physical properties and which is of utility in a wide variety of cushioning applications.Type: GrantFiled: May 31, 1983Date of Patent: February 5, 1985Assignee: Olin CorporationInventors: Maurice C.

Patent number: 4477619Abstract: Reinforcing fabrics or cords, particularly those made from adhesive activated (AA) polyester yarn, or non-adhesive activated (non-AA) polyester yarn, or aramid yarn, maybe coated in a first of two dips in a two-step (double-dip) process, or more preferably in a single-step (single-dip) process, with an adhesive dispersion comprising a solid finely divided reversibly blocked polyisocyanate (RBP), having a majority of its primary particles smaller than 1 micron in average diameter, when the RBP is held in suspension as a substantially homogeneous dispersion with the aid of a hydrocarbyl disperser. The RBP is so held with less agitation than is required to produce a vortex in the dispersion. There is no "flaking" on the fabric after it is dried at a temperature higher than 250.degree. F. for less than about 3 minutes, and heat-set at a temperature above that at which the RBP is unblocked.Type: GrantFiled: October 8, 1982Date of Patent: October 16, 1984Assignee: The B. F.

Patent number: 4456707Abstract: Polyurethane moldings having an inhomogeneously colored surface with color contrasts in fiber-like distribution are made by incorporating colored fibers of a specified type in a polyurethane forming reactionmixture. The colored fibers must have a staple length of from 0.1 to 6 mm, a denier of from 0.1 to 25 dtex, and a coloring agent that does not migrate or dissolve in the polyurethane-forming materials. These fibers are generally used in a quantity such that they represent from 0.1 to 10 wt. % of the polyurethane-forming reaction mixture. Shoe soles, shoe heels, multiple layer soles and padded components are examples of moldings which may be produced in accordance with the present invention.Type: GrantFiled: April 11, 1983Date of Patent: June 26, 1984Assignee: Bayer AktiengesellschaftInventors: Lothar Hille, Heimo Ludke, Nikolaus Hansjosten

Patent number: 4397983Abstract: The invention is concerned with the preparation of polyurethane compositions in which the deleterious effect of gaseous by-products formed in the reaction is minimized. This is achieved by the use of coupling reagents which incorporate a steric hindrance function. The latter does not interfere with the normal coupling reactions between the coupling agent and polymer matrix and filler material but it does prevent such reaction between the coupling agent and filler material as would cause release of low molecular weight compounds occluded by the filler. Since the release of low molecular weight compounds is avoided, the formation or evolution of gases which give rise to unwanted cellularity of the cured composition is at least minimized.Type: GrantFiled: December 28, 1981Date of Patent: August 9, 1983Assignees: Aerofoam Industries Proprietary Limited, Polyeth Marketing Proprietary LimitedInventors: Edward T. Hill, Bernard L. Kaplan, Paul V. Farkas
