  • Patent number: 6492462
    Abstract: The rheological properties of a crosslinkable resin system are modified by the presence of a side chain crystalline (SCC) polymer (or a similar crystalline polymer which melts over a narrow temperature range). The polymer dissolves in the curable system at temperatures above the melting point of the crystalline polymer (Tp), but when the system is then cooled to a temperature below Tp, at least partially forms a separate phase in the curable system. Below Tp, this separate phase substantially increases the viscosity of the curable system (i.e. makes it thicker than the same system without the crystalline polymer). This is particularly valuable for sheet molding composites (SMCs) in which the increase in viscosity makes the composites less tacky, and for dry film resists (DFRs). Above Tp, the curable system containing the dissolved crystalline polymer has a viscosity which is substantially less than its viscosity below Tp.

  • Patent number: 6160038
    Abstract: A method for dispersing solid forms of additives in polymers involves adding dispersions or solutions of additive(s) to a solution of polymer in a tubular mixer (preferably in the presence of a stationary mixer). The mixer leads to a steam precipitation step wherein all fluid ingredients in the mixture are volatilized leaving the solid additive and resin in the desired ratio. This results in a uniform dispersion of the additives in the polymer matrix. As a result of the high dispersion, physical properties of a thermoplastic resin, to which the polymer matrix has been added are preserved. In one illustration, PTFE as a drip inhibitor additive, is added to polycarbonate to obtain a highly dispersed PTFE concentrate of improved drip-inhibition without loss of mechanical properties when added to a thermoplastic molding resin.

  • Patent number: 5830928
    Abstract: The present invention provides a waterborne coating composition which includes a polymeric film-forming resin. The polymeric film-forming resin includes a dispersion of polymeric microparticles prepared by forming, in aqueous medium, a mixture of: (a) an unsaturated, substantially hydrophobic polyester component, and (b) an ethylenically unsaturated monomer component. With various hydrophobic polyesters, the ethylenically unsaturated monomer component of the polymeric film-forming resin includes: (a) an acrylamide or methacrylamide with N-methylol or N-alkoxymethyl functionality, (b) an alpha-beta ethylenically unsaturated compound with carboxyl functionality, and (c) an alpha-beta ethylenically unsaturated compound with no additional reactive functionality. Such a waterborne coating composition has a low V.O.C., provides added stiffness, does not block, and can be applied in such a manner that it does not substantially mask the texture of the nonwoven fabrics and/or textiles over which it is applied.

  • Patent number: 5693714
    Abstract: Rubber particles, to be used as fillers or extenders for various composite polymer systems, are chlorinated by a gas-solid phase reaction with a chlorine-containing gas. A composite polymer containing the chlorinated rubber fillers or extenders exhibits a higher flexural modulus than if prepared using an unchlorinated rubber filler or extender. Chlorination of the rubber particles is carried out by contacting the finely divided rubber particles with a chlorine-containing gas comprising at least about 5 volume percent chlorine. Advantageously, the chlorine can be diluted with air, nitrogen or other essentially inert gases and may contain minor amounts of fluorine. Improved performance is obtained with nitrogen dilution of the chlorine gas over air dilution. Improved polymer composite systems having higher flexural modulus result from the use of the chlorinated rubber particles as fillers instead of unchlorinated rubber particles.
