Acrylic modified epoxy copolymer

The acrylic modified epoxy copolymer can be neutralized via the pendant carboxyl groups to provide a water-dispersible system with good hydrolytic stability. The grafting is presumed to occur onto the methylene hydrogens of the glycidyl group in the epoxy resin ... [Pg.306]

Studies of the particle—epoxy interface and particle composition have been helpful in understanding the rubber-particle formation in epoxy resins (306). Based on extensive dynamic mechanical studies of epoxy resin cure, a mechanism was proposed for the development of a heterophase morphology in rubber-modified epoxy resins (307). Other functionalized mbbers, such as amine-terminated butadiene—acrylonitrile copolymers (308) and tf-butyl acrylate—acrylic acid copolymers (309), have been used for toughening epoxy resins.

An acrylic-alkyd graft copolymer which is water-dispersible was prepared by Walus (30) by copolymerizing methyl methacrylate, butyl methacrylate and methacrylic acid in the presence of an epoxy-modified dehydrated castor oil alkyd which was pre-reacted with lEM. When formulated with NH this gives an air-dry water-dispersible alkyd... [Pg.776]

Oil-base (including oil-modified alkyd resin) paint films should not be used in alkaline environments as the paint will deteriorate owing to saponification alkali-resistant coatings are provided by some cellulose ethers, e.g. ethyl cellulose, certain polyurethane, chlorinated rubber, epoxy, p.v.c./ p.v.a. copolymer, or acrylic-resin-based paints. In particular, aluminium and its alloys should be protected by alkali-resistant coatings owing to the detrimental effects of alkali on these metals. [Pg.612]

Therefore, once the type of modifier is selected, e.g. a statistical copolymer of acrylonitrile and butadiene, its miscibility with the monomers may be varied significantly by changing the nature of end-groups, the fraction of both comonomers in the copolymer, and the molar mass distribution. The same trends have been observed with rubbers based on n-butyl acrylate [73] or dimethylsiloxane [74]. The introduction of acrylonitrile units, polycaprolactone blocks [75], or phenyl groups in the modifiers increases the polarity and the initial miscibility in polar monomers like epoxy resins or bismaleimides [76].

Epoxies can be modified to have low energy surfaces so that they can function in conjunction with silicone-release coatings. For this application, three types of block copolymers (53), each of which consisted of two blocks, were used as surface modifiers. One bloek was a random copolymer of methyl methacrylate (MMA) and 2,3-epoxypropyl methacrylate (GMA), the other was a polymer of lH,lH,2H,2H-heptadecafluorodeeyl acrylate (PFA) which has the following structure.

PP and POM are both semicrystalline and immiscible, thus at w s 10 wt.% they should be compatibilized and impact modified. Since POM can develop strong hydrogen bonding with acidic or epoxy groups, usually acidified or epoxidized PO has been used. For example, POM blends with PP were compatibilized by addition of muconic acid-grafted PP. Another system comprised POM, thermoplastic urethane (TPU), 10-30 wt.% of either PP, PA, or polyester, and ethylene-butyl acrylate-GMA copolymer, with (EBA-GMA) as compatibilizer. [Pg.632]
