This invention relates to the synthesis from PET (virgin, recycled, post consumer, or precursor raw materials) of novel water dispersible or water emulsifiable polyester resins having improved hydrophobicity or non- polar characteristics. These characteristics give the applied film of these dispersions or emulsions much improved water repellency while at the same time retaining their redispersible or reemulsifiable properties. Such resins can be used for many applications in the paper, textile, coatings, paint, construction, and other industries.
L'invention concerne la synthèse, à partir de PET (vierge, recyclé, post-consommation, ou bien matières premières précurseurs), de nouvelles résines polyesters dispersables ou émulsifiables dans l'eau et présentant des cacactéristiques d'hydrophobicité ou non polaires améliorées. Ces caractéristiques confèrent au film appliqué de ces dispersions ou émulsions une hydrophobicité bien améliorée tandis qu'elles conservent leur aptitude à la redispersion ou à la ré-émulsification. Ces résines peuvent s'utiliser pour de nombreuses applications dans le papier, le textile, les revêtements, la peinture, la construction, et d'autres industries.
