  • Patent number: 10414834
    Abstract: There are provided a modified liquid diene rubber that can be used for a curable resin composition and a resin composition containing the modified liquid diene rubber. The curable resin composition containing the modified liquid diene rubber has a much higher curing rate than that in the related art, and the resulting cured product has excellent mechanical properties, transparency, and heat resistance. Produced are a modified liquid diene rubber and a resin composition containing the modified liquid diene rubber. The modified liquid diene rubber includes a modifying group (p) partly containing a (meth)acryloyl group therein and a monomer unit (a1) derived from a conjugated diene compound. A carbon-carbon double bond derived from the conjugated diene compound has a hydrogenation rate of 30 to 95 mol %, and the modifying group (p) has a functional group equivalent weight of 700 to 20,000 g/eq.
    Type: Grant

  • Patent number: 9598507
    Abstract: A modified liquid diene-based rubber (A) including, in a molecule, a modified group (a) containing a (meth)acryloyl group as a part thereof and at least one modified group (b) selected from a dicarboxylic acid monoester and a dicarboxylic acid monoamide, with the proviso that the modified group (b) comprises no (meth)acryloyl group as a part thereof, wherein the functional group equivalent weights of the modified group (a) and the modified group (b) are each in the range of 700 to 40,000 g/eq. Also provided is a curable resin composition containing the modified liquid diene-based rubber.

  • Publication number: 20160229927
    Abstract: Provided is a modified liquid diene-based rubber having an acryloyl group or a methacryloyl group, which is highly compatible with various monomers, such as acrylate or methacrylate having relatively high polarity, which can form a curable resin composition containing the modified liquid diene-based rubber with good workability, which has a satisfactory curing rate during curing, and which is capable of providing the curable resin composition that forms a cured product having excellent mechanical properties derived from the modified liquid diene-based rubber and having excellent adhesion to various materials. Also provided is a curable resin composition containing the modified liquid diene-based rubber.
