%X Based on commercially available polyvinyl alcohol (PVA) stabilised
polyvinyl acetate (PVAc), emulsion adhesives are neither heat</span></span><span><span><span style=\"font-family:&quot;\"> n</span></span></span><span><span><span style=\"font-family:&quot;\">or
moisture-resistant and show weak strength at high relative humidity and high
temperatures. Pre- or post-crosslinking is another method used to manufacture a
conventional vinyl-based homopolymers or copolymers system with improved water
resistance. Vinyl neodecanoate (VeoVa), <a name=\"_Hlk157330654\"></a>N-methylolacrylamide
(NMA), Methacrylamide, methacrylic acid (MAA), and other self-crosslinking
comonomers are typically inserted to produce highly water-resistant vinyl based
homopolymers or copolymers. Additionally, organic crosslinkers like glyoxal,
glutaraldehyde, citric acid, tartaric acid, and the like, as well as inorganic
crosslinkers like acidic metal salts like aluminium chloride, aluminium nitra<span>te, boric acid, and the like, can be used to
prepare the highly water-res</span>istant vinyl based homopolymers or
copolymers. It is also possible to combine the self-crosslinking comonomers
with the organic crosslinkers. Recently, a different hybrid chemistry has been
developed that improves lap shear strength, has outstanding water resistance,
good durability, and doesnĄ¯t require any additional crosslinker agents. Two
distinct polymers were combined to develop hybrid polymers. They usually
involve mixing an organic polymer with a polymer. There are many capping agents
that are used for polyurethanes to produce acrylics that are capped with
polyurethane and used as an oligomer in PVAc wood glue. Here, in this paper</span></span></span><span><span><span style=\"font-family:&quot;\">,</span></span></span><span><span><span style=\"font-family:&quot;\"> we reviewed
the different hybrid chemistry based on polyurethane chemistry for wood bonding
applications.
