Abstract: Macromonomers of formula (I) are new., where R1, R2 are lower alkyl; R3 is H or lower alkyl; and n is polymerisation deg. of at least 5. Macromonomers of formula (Ia), partic. omega-(4-vinyl-)benzoyl-poly 2,6-dimethyl-1,4 phenylene ether (VB-PPE) of polymerisation deg. of the phenylene ether of 5-200 are specifically claimed. In (Ia), n = 5-200. USE/ADVANTAGE - Used for the prepn. of copolymers (claimed). Avoids prior art problems of sepg. copolymers and unreacted monomer. The graft polymers obtd. are useful as adhesives, compatabilisers in polymer alloys or rubber in materials. In an example, 30g poly-(2,6-dimethyl-1,4-phenylene ether) (PPE) (prepd. from p-chloro-2,6-dimethyl phenol) (Mn 13400) was dissolved in 350g pyridine. 10 mols. 4-vinyl benzoyl chloride were added at 0. deg. C, giving VB-PPE after 24 hrs.. 3g VB-PPE and 7g ethyl acrylate were dissolved in 50g toluene, 0.03 AIBN added and polymerisation occurred at 60 deg. C for 30 hrs.. The polymer was pptd. in 4 pts. vol. petroleum ether and 1 pt. vol. methanol and dried. The yield was 88%.

Abstract: Stabilisers for aqueous alkyl diketene dispersions comprise amphiphilic alkylated polyethylene imines prepared by partial alkylation of polyethylene imines using alkyl halides containing at least 5C atoms. Also claimed are aqueous alkyl diketene dispersions containing these stabilisers, used as internal sizing agents for paper pulp. Preferably the polyethylene imines have a weight average molecular weight of 500-50000 (700-30000). The alkyl halides contain 5-30C atoms and are preferably 1-22C alkyl bromides. The degree of alkylation is 1-35 (3-33)%.
