Synthesis, Characterization and Dielectric Properties of Biphenyl Group Containing Polymaleimide and Cyanate Ester Copolymer

In order to improve the solubility and dielectric properties of maleimide resin, polymaleimide (PMI) was prepared from maleic anhydride and polyarylamine containing biphenyl group (PBPPA), which was synthesized from 4,4′‐bis(chloromethyl)‐1,1′‐biphenyl and aniline. The chemical structure and molecule weight of PBPP...

Reinforcement Learning on Benign Facts Amplifies Leakage of Memorized Private Data

Reinforcement learning with verifiable rewards (RLVR) is deployed to make models better at reasoning tasks, but its side effect on what models will divulge is under studied. Here we show that RLVR on facts increases extraction of personally identifiable information (PII) the instruct model had already memorized. We fir...
