摘要

Processes for the preparation of a reactional product, a product containing functionalised polypropylene reaction, polymer solution cast hot, polypropylene film, molded article of manufacture and hot molten adhesive.The present invention relates to the preparation of products containing homopolymers and copolymers of reacionais functionalised polypropylene grafted with carboxylic acid, which can be used as additives for plastics products based on polyolefin, such as adhesives) The hot.Such additives reacionais products can be prepared by: a) providing a first reagent comprising a homo polymer or copolymer of propylene based castSelected a kind of relatively low molecular weight and low viscosity in the molten state; (b) forming a reaction mixture by adding the first reagent to a second reagent comprising an agent of funcionalizau00e7u00e3o based unsaturated carboxylic acid and a The initiator comprising a certain type of organic peroxide; and (c) maintaining the reaction mixture resulting.In a relatively low temperature, between approximately 13 and approximately C 198 198 165 C, for a period of time and under conditions sufficient to form a reaction product comprising polymeric material on the basis of polypropylene grafted with acid and which presents an efficiency of graft Relatively high.
