    • The present invention discloses a method for manufacturing a silicone hydrogel, including the steps of preparing a polyethylene glycol-containing secondary or tertiary amino alcohol, a crosslinking agent having at least two epoxide rings, and a copolymerization mixture capable of performing a radical chain polymerization reaction, wherein the copolymerization mixture contains a linear silicone prepolymer, a silicone monomer, and a hydrophilic monomer, the linking process is activated, by heating to let the epoxide rings of the crosslinking agent open and respectively links with the amino alcohol and an one component of the copolymerization mixture, and completing the radical chain polymerization reaction to obtain a silicone hydrogel. The present invention also provides a contact lens manufactured by the aforementioned method. The present invention distributes and affixes polyethylene glycol of the amino alcohol onto the surface of the silicone hydrogel, thus providing hydrophilicity and electrical charges to the silicone hydrogel.

    • The present invention achieves increased filler interaction by incorporating a small amount (a few units per chain of rubbery polymer) of a conjugated triene monomer, such as alloocimene, randomly throughout the polymer chain of a rubbery polymer or at the chain ends of the rubbery polymer. The incorporation of the conjugated triene monomer leads to the formation of a polymer containing highly reactive conjugated diene units. These conjugated diene units can chemically react with carbon black leading to superior reinforcement. Alternatively, these conjugated diene units can be used for functionalization of the polymer with silica interactive/reactive groups using Diels Alder reactions. This functionalization of the rubbery polymer can conveniently be conducted in a mixer, such as a Banbury mixer, a mill mixer, or the like. The present invention more specifically discloses a rubbery polymer having repeat units which are comprised of (1) an olefin monomer selected from the group consisting of conjugated diolefin monomers and monoolefin monomers and (2) a conjugated triene monomer. The subject invention further reveals a rubbery composition which is comprised of the reaction product of (I) a rubbery polymer having repeat units which are comprised of (1) an olefin monomer selected from the group consisting of conjugated diolefin monomers and monoolefin monomers and (2) a conjugated triene monomer and (II) a dienophile and/or dienophile which is functionalized with a group which is capable of reacting with a filler selected from the group consisting of carbon black, silica, starch, and cellulose.
    • 本发明通过在橡胶状聚合物的整个聚合物链中或在橡胶状聚合物的链末端随机引入少量(每个链的橡胶状聚合物链)的共轭三烯单体如异环烯烃来实现增加的填料相互作用 。 共轭三烯单体的引入导致形成含高活性共轭二烯单元的聚合物。 这些共轭二烯单元可以与炭黑发生化学反应,从而实现优异的增强。 或者,这些共轭二烯单元可用于使用Diels Alder反应用二氧化硅相互作用/反应性基团对聚合物进行官能化。 橡胶状聚合物的这种功能化可以方便地在混合器中进行,例如班伯里密炼机,研磨混合机等。 本发明更具体地公开了具有重复单元的橡胶状聚合物,其包含(1)选自共轭二烯烃单体和单烯烃单体的烯烃单体和(2)共轭三烯单体。 本发明还揭示了一种橡胶组合物,其由(I)具有重复单元的橡胶状聚合物的反应产物组成,所述重复单元包括(1)选自共轭二烯烃单体和单烯烃单体的烯烃单体和(2 )共轭三烯单体和(II)亲二烯体和/或亲二烯体,其可以与能够与选自炭黑,二氧化硅,淀粉和纤维素的填料反应的基团官能化。
