| 20110262755 | Gelcoat Composition and Articles Comprising the Same - The present invention is concerned with gelcoats comprising unsaturated urethane resins containing both acrylate and allyl ether functional groups, which in embodiments provide a desirable combination of a back up time of less than one hour and a longer interval between back up time and tack-free time. In particular, the present invention provides a polymerisable reaction product of: (1) an isocyanate component having two or more isocyanate groups; and (2) ethylenically unsaturated components comprising: (i) an acrylate component having at least one functional group that is reactive with an isocyanate group and at least one acrylate group; and (ii) an allyl component having at least one functional group that is reactive with an isocyanate group and at least one allyl group, wherein the reaction product is in the presence of a reactive diluent monomer suitable for reaction therewith to form a thermoset gel coat. | 10-27-2011 |
| 20110172359 | Crosslinkable Moulding Composition - A crosslinkable moulding composition comprises: (1) a functionalised isocyanate product having at least six ethylenically unsaturated groups which is the reaction product of (i) an isocyanate component having an isocyanate functionality of two or more, and (ii) an ethylenically unsaturated component having at least one functional group that is reactive with an isocyanate group of the isocyanate component and at least two ethylenically unsaturated groups; and (2) a monomer component comprising a cross-linking monomer having at least two ethylenically unsaturated groups, wherein at least one of an ethylenically unsaturated component (ii) and/or a monomer component (2) are selected to have at least three ethylenically unsaturated groups. The moulding compositions are especially suitable for reinforcement and thermal curing. Example crosslinked resins derived from such moulding compositions are shown to be capable of achieving high heat deflection temperatures, often in excess of 260° C. | 07-14-2011 |
| 20100272661 | PROCESS FOR THE PREPARATION OF INVERSE LATEX OF ACRYLAMIDE-BASED POLYMERS AND COMPOSITION COMPRISING SAID LATEX - Process for the preparation of a an inverse latex including from 20% to 70% by weight and preferably from 25% to 50% by weight of a branched or crosslinked polyelectrolyte, characterized in that the polyelectrolyte is a copolymer of 2-acrylamido-2-methylpropanesulfonic acid partially or totally salified with acrylamide and optionally one or more monomers chosen from monomers containing a partially or totally salified weak acid function and/or from neutral monomers other than acrylamide, the production process including the control of the pH in the initial aqueous phase; Cosmetic, dermopharmaceutical or pharmaceutical composition including the inverse latex directly obtained by the process. | 10-28-2010 |
| 20100233108 | PROCESS FOR THE PREPARATION OF INVERSE LATEX OF ACRYLAMIDE-BASED POLYMERS AND COMPOSITION COMPRISING SAID LATEX - Process for the preparation of a composition including an oil phase, an aqueous phase, at least one emulsifying system of water-in-oil (W/O) type, optionally at least one emulsifying system of oil-in-water (O/W) type, in the form of an inverse latex including from 20% to 70% by weight and preferably from 25% to 50% by weight of a branched or crosslinked polyelectrolyte, characterized in that the polyelectrolyte is a copolymer of 2-acrylamido-2-methylpropanesulfonic acid partially or totally salified with acrylamide and optionally one or more monomers chosen from monomers containing a partially or totally salified weak acid function and/or from neutral monomers other than acrylamide, the production process being characterized in that the preparation of the aqueous phase includes the dissolution in the aqueous medium of solid 2-acrylamido-2-methyl propanesulfonic acid before neutralization. Cosmetic, dermopharmaceutical or pharmaceutical composition including the inverse latex directly obtained by the process. | 09-16-2010 |
