Laromer EA 9143 (75% standard epoxy
acrylate in 25% GPTA)
Although shear degradation has been correlated to ultrasonic degradation for the degradation of polystyrene (38), few other studies have shown that the degradation of alkyl
acrylate and alkyl methacrylate follow the same order for both ultrasonic and thermal degradation (33), (37).
While monomers are very strong irritants and allergens, fully polymerized
acrylates are relatively inert.
Abstract A series of UV-curable hyperbranched polyurethane
acrylate (HBPUA) oligomers were synthesized with isophorone diisocyanatc (IPDI), hyperbranched polyester Boltorn H20 (HBP) and hydroxyethyl
acrylate (HEA).
Both
acrylates and methacrylates are used to improve the performance characteristics of various polymers, such as polyethylene, polypropylene and polyvinyl chloride.
In our second approach we attempted to create a soft touch coating with an existing trifunctional
acrylate crosslinker and low functional
acrylate monomers (AM) as the soft connecting segments instead of difunctional urethane
acrylates.
The UV
acrylates business, which had been part of Cognis' Functional Products strategic business unit, manufactures and sells monomers and oligomers for UV applications marketed under the Photomer brand name.
The UV-free radical polymerization of multifunctional
acrylates also leads to the formation of heterogeneous networks through generation of microgels.
The solubility parameter of PBD-DA is much closer to the hydrophobic elastomers than the monomeric multifunctional
acrylates.
The Dow Chemical Company, Danbury, CT, has acquired the Celanese
acrylates business.
The Elvaloy AC resin family includes eight ethylene methyl
acrylates (EMAs), four ethylene ethyl
acrylates (EEAs) and six ethylene butyl
acrylates (EBAs).
Acrylates are also widely used as co-monomers and property modifiers in specialty plastics, including ethylene ethyl
acrylate (EEA) and ethylene methyl
acrylate (EMA).
