Patent number: 6492462Abstract: 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.Type: GrantFiled: December 19, 2000Date of Patent: December 10, 2002Assignee: Landec CorporationInventors: Steven P.

Patent number: 6020416Abstract: The invention pertains to aqueous blends of colloidally dispersed polymers for use in making organic coatings which are hard and ductile at ambient temperature, which coatings remain stiff and elastic at temperatures well above their film-formation or drying temperature. In particular, the invention relates to specific combinations or thermoplastic blends of polymers of very high molecular weights. Such blends produce smooth, essentially crack-free coatings when dried conventionally under atmospheric pressure. Such blends are capable of developing the desired balance of properties without conventional amounts of volatile organic coalescing aids and without the need for chemical cure.Type: GrantFiled: February 2, 1998Date of Patent: February 1, 2000Assignee: E. I. du Pont de Nemours and CompanyInventors: Stephen Mazur, Gerald Donald Andrews
