Patent ID: 8445566

Claim:
A process for continuously preparing a reactive polymer, the process comprising: reacting a mixture (A) comprising one or more compounds having structure (A1) wherein R 1 =alkyl or phenyl group, R 2 , R 3 , R n =hydrogen or alkyl group, and n=0, 1, 2, or 3; or one or more compounds having structure (A2) wherein A=alkylene or phenylene, R 4 , R 5 , R 6 , R 7 , R m , R o =hydrogen or alkyl group, and m, o=0, 1, 2, or 3; or mixtures of one or more compounds having the structure (A1) and (A2), wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R n , R m , and R o can be identical or different and substituted or unsubstituted, A can be substituted or unsubstituted, and m and o can be identical or different, with phenolic resins (B), in an extruder, flow tube, intensive kneader, intensive mixer, or static mixer, by mixing and reaction with introduction of heat, and subsequently isolating an end product, wherein a residence time of starting materials, which are mixture (A) and phenolic resin (B), in the extruder, flow tube, intensive kneader, intensive mixer, or static mixer, is from 3 seconds to 15 minutes, and reactants are reacted at a temperature of from 150° C. to 200° C., and then rapid cooling is carried out, with the temperature decreasing by more than 50° C. within less than 60 seconds.
