Abstract
Adhesive composition for bonding and filling large assemblies, including a mixture of about 5 percent to about 75 percent by weight of a thermoplastic polymer, about 0.5 percent to about 35 percent by weight of a polyester resin or vinyl ester resin, and about 20 percent to about 80 percent by weight of an alkyl acrylate or methacrylate monomer.
Claims32
A polymerizable adhesive or filling composition comprising
- about 5 to about 75 percent, by weight, of a blend of
- a) at least one crosslinked or partially crosslinked polymer or elastomer, and
- b) at least one soluble thermoplastic polymer or elastomer,
- about 0.5 to about 35 percent, by weight, of a vinyl ester resin derived from the reaction product of a polyepoxide and an unsaturated monocarboxylic acid and the subsequent addition of a styrene monomer, and
- about 20 to about 80 percent of an alkyl acrylate or methacrylate monomer.
2 more elements
A polymerizable adhesive or filling composition comprising
- 1) from about 5 percent to about 75 percent, by weight, of a blend of polymers comprising
- a. a soluble component comprising non-crosslinked thermoplastic polymers selected from the group consisting of polychloroprene elastomers, nitrile elastomers, acrylic elastomers and copolymers, copolymers and multipolymers containing acrylonitrile, styrenic and acrylic monomers, acrylonitrile butadiene styrene resins, diene-based polymers, copolymers and multipolymers based on butadiene, isoprene, ethylene-propylene and ethylene-butylene in combination with styrene, acrylonitrile and acrylic monomers, block copolymers, chlorinated polyethylenes, chlorosulfonated polyethylenes, and reactive liquid polymers, and
- b. an insoluble or partially soluble core shell impact modifier,
- 2) from 0.5 to 35 percent by weight of a component selected from the group consisting of
- a. an unsaturated polyester resin derived from maleic acid, fumaric acid, phthalic acid, orthophthalic acid and isophthalic acid,
- b. a terminally unsaturated vinyl ester resin derived from a polyepoxide, and
- c. mixtures of the above, and
- 3) from 20 to 80 percent by weight of an alkyl acrylate or methacrylate monomer.
