Patent number: 6403711Abstract: A high elongation, low 100% modulus composition comprises a copolymer dispersed in a continuous phase polysiloxane. The copolymer is made from high amounts of at least a monomer which is capable of forming a low Tg polymer and relatively low amounts of at least a monomer which is capable of forming a high Tg polymer. The monomer forming the low Tg polymer can be an alkyl acrylate whereas the monomers forming the high Tg polymer can be a vinyl ester, an acrylonitrile or derivatives thereof, a vinyl substituted aromatic such as styrene, an alkyl methacrylate, and the like. The composition has good adhesion to substrates as well as good viscosity aging, and can be utilized in caulks or sealants.Type: GrantFiled: January 10, 2000Date of Patent: June 11, 2002Assignee: Noveon IP Holdings Corp.Inventors: Wei-Yeih Yang, Melvin Dale Beers, Ta-Min Feng

Patent number: 4820763Abstract: A polyblend of poly(vinyl chloride) ("PVC") and a copolyester ("CPE") consists essentially of three components in a structure --(MR).sub.x --(MQ).sub.y -- wherein (MR).sub.x represents an ester segment with a repeating unit of mol wt 204 or 220, (MQ).sub.y an ester segment consisting of a residue of a polyester diol, so that the CPE is non-elastomeric and has a m p in the range from above 170.degree. C. to about 220.degree. C. Then the CPE provides a limited plasticizing function in PVC when the CPE is used in the range from about 30 to about 70 parts by wt based on 100 parts of the polyblend. The lack of a typical plasticizing function is evidenced by a relatively flat modulus curve, preferably one having a slope less than 1.2.times.10.sup.5 psi per unit weight of PVC in the polyblend.Type: GrantFiled: April 14, 1987Date of Patent: April 11, 1989Assignee: The B.
