Abstract: The present patent of invention describes the obtention of lasers in solid condition of dyes of the family of Rhodamines. More particularly, it describes lasers in which said dye or chromophore is to be found covalently anchored to a solid matrix, consisting in a transparent organic polymer and suficiently stable to the pumping radiation. Its application is the production of the laser emittance by an organic dye in a solid matrix and polymers containing rhodamines.

Abstract: A vinyl graphic marking film or label coated with a pressure sensitive acrylic adhesive designed to achieve high or permanent adhesion to polymeric low energy surfaces is disclosed. In addition to good adhesion to low energy surfaces, the graphic marking film or label may have microperforated or micro-rough edges which initiate tearing when removal is attempted. The article maintains flexibility and film strength for easy fabrication in graphic marking film or label manufacture.

Abstract: The present invention is directed to new metal cation neutralized high acid ionomer resins and to golf ball cover compositions containing these new resins. When the new high acid ionomer resins are utilized to manufacture a golf ball, the golf ball produced thereby exhibits properties of improved distance without sacrificing characteristics such as playability and/or durability when compared to low acid ionomer and/or low acid/high acid ionomer blends.

Abstract: A method of preparing a functionalized polymer comprising the steps of initiating the formation and propagation of an anionically-polymerized living polymer, and terminating the propagation of the living polymer by reacting the polymer with a terminating agent selected from the group of agents defined by the formulas (III), (IV), and (V) where C is a carbon atom, S is a sulfur atom, X is a halogen atom, R2 and R4 are independently selected from hydrogen and carbon-based moieties, and where the phenyl groups are selected from unsubstituted and substituted phenyl groups.

Abstract: The present invention is directed to a golf ball comprising a soft core and a hard cover to produce a resulting molded golf ball having a reduced spin rate. The golf ball of the present invention has an enlarged diameter which serves to further reduce spin rate. The resulting golf ball exhibits properties of reduced spin without sacrificing durability, playability and resilience.

Abstract: The present invention provides a surface-crosslinking process of a water-absorbent resin to obtain a water-absorbing agent which has high absorption speed and excellent absorption capacity under a load (a water-absorbent resin which has specific or larger values of properties). In a process comprising the step of adding a crosslinking agent to a dry water-absorbent resin powder to thereby crosslink the neighborhood of its surface, the surface-crosslinking is carried out while the resin powder having a weight-average particle diameter of 200 to 1,000 &mgr;m is pulverized.

Abstract: This invention relates to an aromatic ester (meth)acrylate dendrimer composed of the core formed by an aromatic polycarboxylic acid and the branches formed by an aromatic compound containing one hydroxyl group and two carboxyl groups and represented by the following general formula (1) and also to a curable resin composition which contains the dendrimer and a polymerization initiator as essential components, is low in viscosity and highly curable, and forms a coating film with excellent heat and moisture resistance.

Abstract: The present invention provides a high temperature continuous polymerization and condensation process for preparing a polymeric product. The process includes continuously charging into a reaction zone: at least one radically-polymerizable monomer having a radically polymerizable group and at least one condensation reactive functionality; and at least one modifying agent having a functional group capable of reacting with the condensation reactive functionality. The reaction zone includes at least one primary reactor, but may, and preferably does, contain a secondary reactor. The process further includes maintaining an effective temperature in the primary reactor to cause polymerization of the monomer and to allow at least a portion of the condensation reactive functionality to react with the functional group of the modifying agent.

Abstract: The invention relates to antimicrobial non-cross-linked polymers which are constituted of an ester and/or amide resin to which quaternary ammonium salts are bound by a covalent bond which is potentially reactive with water, the quaternary ammonium content being at least 1 M/kg, a well as to the use thereof for the preparation of a material having antimicrobial properties and to their methods of preparation.

Abstract: The invention relates to polymethacrylate acid-polyalkylene oxide block copolymers, to a process for their preparation and to their use as dispersants or suspension stabilizers for pigments and fillers, e.g. for metal oxides in ceramic materials, for pigments in inks used in ink jet printing and for fillers in thermosplastic and thermoset polymers.

Abstract: Methods are disclosed for enhancing the toughness, e.g., resistance to cracking upon flexation, of coatings made from cycloaliphatic epoxide derivatives wherein the cycloaliphatic epoxide derivative is a cycloaliphatic epoxide ester of a hydroxy-functional compound containing at least one branched, 1,2-alkylene oxide unit. Processes for making the cycloaliphatic epoxide derivatives and coating formulations comprising the cycloaliphatic epoxide derivatives are also disclosed.

Abstract: An absorbing agent has a diffusing absorbency under pressure of not less than 25 g/g when 60 minutes elapsed after absorption is started, and a water-soluble content is above 0 percent by weight and not more than 7 percent by weight. The absorbing agent is prepared by surface-crosslinking a precursor of the absorbing agent obtained by performing an aqueous solution polymerization of a hydrophilic unsaturated monomer having not less than 50 mole percent neutralized acrylic acid as a main component using a specific crosslinking agent having a main component composed of an ester compound of a specific polyhydroxy alcohol and an unsatuated carboxylic acid, and a high-boiling component having at least two alcohol structures in a molecule as a specific ratio.
